16x DVD-R Drives Planned for 2004 168

I'm planning to buy a high end dual G4, but I'm waiting for Apple to up the specs on components (but NOT the CPU for a change) FSB, RAM, GPU... If I pay $5000 on a computer, I want the biggest, baddest machine available, and 8x or at least 4x DVD writing, 533MHZ FSB with Radeon 9700Pro should be default. Except for the BTO radeon, I'm have no other options but wait...
Re:PowerMac schedule ? (Score:1, Flamebait)
I hope you do realize that the 533mhz FSB that intel is claiming is really a 133mhz bus that is quad-pumped (similar to agp which is 66mhz, double- quad- or 8way-pumped to give higher bandwidth but worse latency). This is not the optimal solution, and is certainly a far cry from a true 533mhz fsb.
also- if you want the biggest, baddest machine available for $5000, you might want to look into dual athlons (or dual xeons if they will fit into the budget). Either one of these (at top available clock speed) will mop the floor with your dual G4 (yes, even in photoshop and in video editing), and will likely cost less to boot. Apples are for people who like their computer to look pretty as opposed to being more useful.

Is that so? Paralellism and efficiency depends on the application in use. If the bus, with one line, can always be ready to carry the next instruction without blocking the prior one, then sure, it's a great solution.
If there is any reason for hesitation of the bus, then instructions will queue. It is just like SMP processors. It's not always guarnateed that any processor will be given it's full capacity to process. Is why SMP works out a little better as it handles extra instructions.
Optimal solution, no, but a "true 533 bus" might have latency problems if the queue gets full.

Same with Intel's 4x bus. It really does transfer data as fast as a 533mhz bus that only transfers once per clock. There really isn't any disadvantage to it. It's just a mor advanced way of translating data.
It is real similar to modems. At first, modems just transmitted data by using 2 tones, one for on one for off. They continued to scale the rate of transmission faster and faster. But eventually (at 300 baud) they were reaching the limit. So modems started using better signaling (multiple tones) to continue to increase the effective data transmission rate without increasing the rate of tones.

Zen TrueX (Score:2, Informative)
You may remember Zen Research [zenresearch.com] who created the TrueX technology found in the old Kenwood 72x [smartcomputing.com] drives. I believe these used 7 heads for reading data. However, the technology seems to have died, along with the company. I remember reading reports of the drives not being 100% compatible, having speed issues, and having high failure rates.
they got whapped by a couple things (Score:4, Interesting)
Second is that the tracks on CD-Rs aren't completely parallel. CD-R tracks have a slight wobble to them to allow the writer to determine the rotation rate of the disk (and thus how far they are along) while writing. The wobble is a fixed frequency, and thus as the track lengths change from inside to outside, the wobble does not nest up nicely between tracks like Pringles chips. So, all of a sudden, tracking one track didn't keep the other 6 readers on line.
Finally, they got killed by copy protected CDs. Copy protected CDs purposely have bad sections to them. With most CD drives you read up until you get to the bad spot and then the drive freaks. On a Zen, the drive would freak 6 rotations early. This made it incompatible with copy protections and slowed the read speeds in the protected area.
To be honest, the technology, while neat, had a fatal flaw from the start. On a single head drive, when the disk rotates around once the head is advanced to new data on the next spiral. On the Zen, the head is ONLY advanced one spiral. Thus, 6 of the heads are reading the same spiral that the head next to them read last time around and only one head is reading new data. Thus, you have to get off the spiral, move the head, and then servo lock to the spiral again. And once of the slowest things a CD-drive can do is servo lock to the spiral. This is why seek times are in the 50ms range (used to be 150ms!). So you get data at 7X speed, then have to pick up and move to another spot for 1/20th second, then get data at 7X again. It's no wonder the drives rarely produced the speeds they spoke of.

CD and DVD store the data as a continuous spiral on the disc, so while it is easy to have multiple read heads I think it would be very difficult to have multiple write heads.
