Perpendicular Hard Drives: the future for DAPs

comet

As has been mentioned before here perpendicular hard drives are going to offer up to 10 times the capacity that existing drives can offer.
Well Toshiba has just produced a 40GB one so we can hope to see more of them pretty soon I'm sure and it probably won't take long for them to be in the latest personal audio players. Here is a cool animation explaning how those perpendicular drives work

Well I feel inspired, I have to admit!
Bits doing Boogie Nights - who says technology isn't user-friendly!

But seriously, this should be fantastic when it becomes widespread. Ten times the storage with the same size? Can't possibly lose there.

Eh. Do you understand how hard this will be to implement on a larger scale?
Also, the price of such drives will be at first extremely high, as the companies try to recoup their R&D losses.
Its been projected that buying 10 standard 500 gig drives will be cheaper than buying 1 5tb drive using the perpindicular bit technology.

I think you are trying to be a bit too smart there, I wasn't talking about drives of scale 10 x 500GB!!, don't you think thats a bit down the road, I was talking about practical sizes for personal music players!

Toshiba has begun shipping what it claims is the world's first perpendicular hard disk drive.

The 1.8in unit is pitched at consumer electronics products - think iPod and Toshiba's own Gigabeat player - and provides 40GB of storage on a single platter, the largest single-platter capacity yet achieved on a 1.8in drive, Toshiba claimed.

Toshiba's non-perpendicular 40GB, 1.8in HDD, the MK4006GAH, requires two platters to achieve the same storage capacity as the one-platter MK4007GAL. The GAL is 5mm thick and weighs 51g, compared to the GAH's 8mm thickness and 62g weight.

That will allow the likes of Apple to offer either slimmer, lighter music players or use the space freed up by the slimmer HDD to increase the size and capacity of the battery. Apple already uses Toshiba's 1.8in HDD family in the iPod.

Toshiba said it expects to introduce a two-platter, 80GB version later this year. Both drives spin at 4200rpmm, provide a parallel ATA-100 interface and offer a 15ms average seek time.

Perpendicular recording increases disk capacity by aligning the millions of magnetic domains at 90° to the disk's surface rather than parallel to it. The upshot is a data density of 206Mb per square millimetre, Toshiba claimed.

However, its claim to be the "first company in the storage industry to commercialise" perpendicular recording is likely to be questioned by a rival HDD maker.

Last month, Japan's Showa Denko KK (SDK) said it has become the first manufacturer in the world to put a perpendicular hard drive into mass production - also a 40GB, 1.8in model.

Indeed, Toshiba comes to the market later than planned. When it announced the 40GB and 80GB perpendicular drives back in December 2004, the products were scheduled to enter mass production in calendar Q2 and Q3, respectively.

Almost all other HDD manufacturers are pursuing perpendicular technology as the next stage in the evolution of magnetic storage. Seagate, for one, is expected to release a 2.5in, 160GB perpendicular HDD for notebooks in Q4. ®

OMG - apart from being a cool Idea ... that flash movie is the funniest bit of computer componant advertsing I have EVER seen !!!

Hmm reckon they drafted the simpsons artist and voices?? ..(sings) ...."now I'm an ammendment to be ...... "
