TDK 2 5TB Hard Drive Plans
Advances in TDK's hard drive technology could lead to another large boost in the capacity of hard drives within a few months, a roadmap presented this week shows. The storage firm is currently going through qualification tests of 640GB drive platters that would fit into a typical 3.5-inch drive and so would allow significantly more storage than existing 2TB drives from Hitachi, Seagate and Western Digital. A premium but commonplace four-platter drive could hold just over 2.5TB of data.

TDK recording HDD density
At the CEATEC show kicking off today in Japan, TDK announced it has achieved a new milestone in surface recording density for hard disk drives thanks to its prototype TMR head. The company achieved the world’s highest surface recording density at 803GB/inch2, which could result in a typical single 1.8-inch double-sided disk having the capacity of 260GB. The TMR head is the same one as introduced in 2007, although TDK engineers have increased its magnetoresistance ratio by more than 80 percent while keeping its bond resistance low.

TDK's micro SATA SSDs
TDK will debut its HS1-series solid-state disk drives at the Computex Taipei 2008 show due to start tomorrow in Taiwan. At 1.8 inches, the drives are the smallest on the market to use a Micro SATA interface, and are meant for notebook computers and industrial devices. The drives are available in 16, 32 and 64GB capacities, and use single-level cell NAND flash memory. Prototype versions of the HS1 drives were first shown at CEATEC in 2007, and TDK says are now ready for use in industrial devices.
