We should expect to see 1TB hard disk drive products within 6 months

Seagate Technology has just released information to DailyTech with regard to the company's upcoming highest capacity hard disk drive to date. At 1TB, if no other hard disk drive manufacturer can catch up, Seagate will have the highest capacity hard drive product to market first.

The 1TB hard disk drive will be based on perpendicular recording technology which packs bits tighter onto the magnetic platter by positioning them perpendicular to the platter as opposed to linear recording which positions bits horizontally. The perpendicular recording technology, which has been in use by Seagate and its platter supplier for over a year now, will be put to the test as Seagate states the 1TB product will implement fewer platters and heads to improve the performance of the drive.

In a statement to DailyTech earlier today, the company claimed:
Seagate’s 1TB hard drive will be our second generation 3.5-inch hard drive to feature capacity-boosting perpendicular recording technology, and it will use fewer heads and discs than similar-capacity products we expect to see from our competitors. It is clear that fewer heads and discs, along with our proven perpendicular technology, can increase drive reliability, and also reduce operating temperatures, power consumption, noise, and weight.
It is confirmed now that we should expect a 1TB Barracuda from Seagate Technology to hit the market in full force sometime in the first half of this calendar year.   Seagate was also the first company to announce a 750GB hard drive last year.  No company has since announced a drive with 750GB or greater capacity.

I think its a matter of fabrication not space. They already have the equipment and production lines to build 3.5" and notebook drive casings and such. The only thing that changes are the platters.

If they go to 5.25" drives, they have to redesign everything from the read head/arm mechanism to the casing. They would also have to redo the production line. It's probably not worth it for the manufacturer, but for the consumer it wouldn't be too bad since most people don't use up all their 5.25" slots.

P.S. Cooling may also play a factor.

I highly doubt they would have to redesign the read-head, as this portion of a HDD is matched to the type of magnetic material used on the usrface of the platter, not platter size. You are correct that a new spindle arm would have to be developed.

And yes, I know what I am talking about, seeing as how I examined and allowed most of the patents that serve as the foundation for Seagates current product line.
