New, Flexible CDs Arrive 332

Mortin writes "A company called Flexstorm has developed a new type of CD, dubbed flexCD, that is about 140 microns thick, 1/10th that of a normal CD, and most importantly flexible. The technical specs on this new technology are quite impressive, boasting a weight of only .6 grams on the flexCD 80. Producing a flexCD also only takes .3 seconds, less than that of a normal CD."

  • They are pushing a flexable cd that plays in a standard cd drive with the use of an adapter.

    So the disks must be the razor.

    OTOH if these were availavle as CDR/RW it might make storage easier if you can reuse the adapters or get a drive that plays them natively.

      I don't think that's such a good idea. Anybody with special equipment could probably read whatever's left of the tracks on the shards of CD. One shard could hold many kilobytes of contiguous data; even entire documents.

      Shredding a CD is kind of like printing all of your documents onto a single mile-long roll of paper, then slicing the paper into 1-foot long pieces. You could get a lot of info off of any one chunk.

      I'm old enough to remember when some books and magazines included analog records printed on sheets of plastic ... particularly music instruction books, and things of that nature.

      "Sound Sheets", they were called.

      Memories:

      • "Sound Sheets should not be used with automatic record changers."
      • "Place Coin Here If Sound Sheet Slips"

      I remember as a kid, when Pierre Elliot Trudeau did that big constitution thing with the queen back in 1981, the newspaper came with Sound Sheets of the Canadian national anthem. Somewhere, I still have that and a few other sound sheets.

      One of them is a little mutilated. At the ripe old age of 7, I *had* to know what would happen if I put it onto the old BSR record changer.

      And now, it's consoling that a new generation shall know the horror.

    According to the specifications, this would require an adaptor to play in existing CD drives.

    If they're pushing this as a supplement to advertisements (distribution via mail, magazine, what have you), how are they going to get the adapters to people? How are they going to overcome the barrier of getting people to actually use the adapters?

    • you're right. however, you are thinking 'today' when they are thinking 'tomorrow' ... this isn't something we'll see for a while (unless the adapter is simply a case or a flash program).

      when cdrw came out, no cdroms could read them. soon after, ALL cdroms could read them. similarly with this (if it flies, and it should); cdrom/dvdrom and writers released after some date in the future will all be able to read this new technology, and at that point, you'll see flexible cds in the mail and in your cereal boxes.

      problem is getting this standardized and implemented into future drives. ...and let's not forget DVD players and CD audio systems -- great for the car!
    • In addition to the obvious comment "next-gen drives won't require an adapter", you're also missing the fact that you can ship a magazine with one adapter and fifty FlexCDs.
    • they've been secretly shipping these adapters for years in CD-R media, what do you think those clear top discs are for? :p
    • For their "FlexCD" to be playable in regular CD drives, it has to conform to the CD standards.

      A regular CD consists of a reflective data layer (aluminium in the case of a "pressed" CD) protected on the top by 10-20 microns of lacquer and on the bottom, by 1.2mm of polycarbonate. CD drives are therefore designed so that the laser focussing system takes the refractive index of polycarbonate into account: the laser is only in focus if the CD has an optical depth of 1.2mm*1.55 (the refractive index, N, of polycarbonate) = 1.86mm.

      If these FlexCDs are 1/10 of the thickness of a regular CD, then either they have to be made of a material with a refractive index ten times larger than that of polycarbonate (show me one!) or they need to use an adaptor (a "spacer" of some kind, perhaps just a disc of transparent plastic!) to keep the data layer at the laser's nominal focus.

    And for non-technical people (the ones that can't set the time on their VCR), they're not going to be able to figure out how to use the adapter and will likely end up destroying their CD players, particularly if they try it with a slot-loading one.

    Sure, it will be great for people who like the CD inserts in magazines, and may be the best thing in the world for them, but I've yet to find an insert that would make me want to keep around an extra caddy just so I could play it. But then again, it would be nice to be able to fold up a CD and stick in an envelope instead of buying the special CD protective packages, so it might work.

      Actually, I like caddies. I'm kinda pissed that I couldn't buy a caddy drive when I built my new Athlon XP last week. The old caddy drive was 2X and I just couldn't live with the speed anymore, so I had to cave and get a tray drive. Ugh.

      Try giving games to 3 year olds and see how long the CDs last. Then put them in caddies and see how long they last (hint: case 1, about 3 days, case 2, 6 years and counting).
      • What would have been perfect is if the cd format had originally been done with a plastic case around them, just like a 3 1/2 inch floppy disk. Unfortunately, the guy who thought up cds based them on records, and just didn't really think of a protective case.
    • Maybe not, I always hate taking a cd-rom or DVD out of the jewel case for fear of the plastic breaking and 12-24 bucks going down the drain. I'd much rather have a flexable, break resistant media and a broken adaptor costing 50 cents anyday.
    • Who remembers CD caddies? And how much you hated them? Why would you want to go back to that?

      Caddies made sense if you had several and you needed to switch CDs in your drive frequently. With six caddies, you could put each of your five most frequently used CDs in its own caddy. Then, when you want to change, you eject one caddy and slap another in. No opening jewelboxes, no delicately handlind a CD by the edge, no carefully placing it in a tray. Just eject and insert. Simple as a floppy. And back in the days when a 100Mb hard drive was considered big, people did a lot of CD-swapping.

      The problem is that the drive manufacturers decided to shave a few bucks off the price of a drive by only including one caddy with the drive. Thus, instead of making things easier, the single caddy actually made things harder, because in addition to opening the jewelbox, etc, you now had to open the caddy each time and gingerly insert the CD. No surprise that people jumped at motorized trays when they finally appeared.

      Nowadays, of course, hard drives can hold a hundred CDs worth of data on them, so no one needs to swap CDs much anymore.

    This isn't as great as it sounds, because you have to "sandwich" it in their plastic adapter to get your CD player to read the disk. Since no one has any of their adapters sitting around the house, anyone who wanted to mail one of thess flexCDs out (which is supposed to be one of their main applications) would also have to send out the rigid plastic pieces, reducing the weight and flexibility advantages. If it ever catches on and people start keeping plastic adapters around the house, that might become unnecessary, but I can see this tanking because people can't figure out why their CD player/drive doesn't like this flexible piece of plastic.

    • That's because you are not in the business of sending out thousands of promotional CDs. Lower weight means lower postage. flexibility means new ways of packaging for promotional handouts. They say they can also automatically insert them in magazines thereby reducing the cost of doing covermounts since the case isn't necessary. And they're quicker to print.


      These aren't aimed at the consumer. They are aimed at the promotions industry.

  • if they are 140 microns thick or whatever, wouldn't they be susceptible to tearing? I mean basically this is just like the foil data layer of a cd with very little protection. this would also make them more vulnerable to scratches and whatnot because you dont have a millimeter or so of plastic between the face and the data. a scratch that would not affect a normal cd may very well scratch all the way to the data layer of a thin cd.

      The AOL CDs I get in the mail don't hold up very well either. They tend to break on the second or third (accidental) bending. They also scratch very easily, especially if I accidentally scratch them with a razor blade. Finally, after being broken in half and scratched, they don't make very good frisbees. I was kind of hoping for better things from this flexible format.

    • Regular CDs aren't very durable, either. On the label side, all that protects the data from damage is a very thin layer of sprayed-on laquer. Scratches through this laquer are generally fatal to the data beneath, and are troublingly easy to create.

      The flexible CDs also use a very thin layer of sprayed-on laquer.

    Being flexible presents some advantage in the ad business as it becomes possible to send CD like junk mail. I (don't really) look forward to the days of getting Pre-approved credit card mail on this media. However, the format becomes quickly an inconvienience when you decide to keep and use the media. As an example, I remember when the DVD expert group was debating over as to protect the disc in the casing or not (like the Panasonic PD disk.) They decided not to, to the biggest regret of companies like Blockbuster who are irritating their customers by renting DVD with scratches and digs all over (I've got one of these DVDs with a cigarette burn in it!)

    I really like the tape format, and I enjoy the mini disc (MD) style, allowing me to throw medium on the desk without caring if it will get scratched. The MD format is almost perfect for me. It's smaller than CDs and fit in backpacks. It's too bad that it hasn't become more popular with increase storage and broader adoption by computer manufacturers.

    Okay, so have they invented a flexible CD? Not really. All they've done is separated the data layer from the rigid plastic layer, so that people will hopefully own only a few of the rigid "adapters" and loads of the data-handling flexCDs. FlexCDs are (a) easier to break than ordinary CDs (because there's no plastic layer protecting the thin data layer, and (b) place more of the cost of playing CDs on the consumer, since producers won't have to pay for the adapters after a while.

    Since they're less rigid and have less total mass to 'average out' any irregularities, what happens when there's a small variation that slightly unbalances the disc? This wouldn't affect audio players, but I wonder if their stability would be insufficient to handle much higher speeds. I didn't see any specs on average maximum read speed.
    • Since they're less rigid and have less total mass to 'average out' any irregularities, what happens when there's a small variation that slightly unbalances the disc?

      I think the issue is not so much if there's an imbalance in the disc to begin with, but that the centrifugal force at high rotational speeds is enough in itself to warp the disk. IIRC, when the CD was introduced, Philips estimated the maximum speed at something like 48X. This has turned out to be pretty accurate - note that today's CDROMs have only been able to significantly break this barrier by using multi-beam heads at lower rotational speeds. I have to admit though - I don't know if they did that just to reduce noise/wear/cost, or whether it was due to the mechanical limits of the CD.

  • I think that the CD has to be quite flat for the laser to stay focused. So I assume that their adapter sandwiches the flex disk between two sheets of plastic.

But get a little dust on it, and the disk is no longer flat inside the sandwich...

    here's the specs in html [adobe.com].

    basically, there are two flexCDs, named 80 and 120 for their sizes in milimeters. The 8cm disk holds 200mb and the 12cm disk holds an unspecified amount (hopefully 702mb). each disk is 1/10th the thickness of a cd. standard minicd is 8cm and standard cd is 12cm. a 3.5" floppy is 9cm x 9.4cm.

    the adapter has two parts which sandwich the flexCD and go in the non-supporting cdrom drive.
