Seagate hard drive stores 100 GBit/inch²

Seagate claims it has set a new record for hard drives. In one experiment, 100 GBit per inch² were saved. The individual components are almost ready for series production. The test system achieved a transfer rate of up to 256 MBit/s.

According to its own information, Seagate has 100 GBit/inch² set a new record for data density for hard drives. The record is said to have been achieved with components that will soon be ready for series production. In the experimental setup, the platters, the individual magnetic disks in a hard drive, were rotated at 4000 revolutions per minute, the track density, according to Seagate, was 149,000 TPI (tracks per inch), with a recording density of 680,000 BPI (bits per inch). With these properties, the test system achieved a transfer rate of up to 256 Mbit/s. Now disks with a record data density of 100 GBit/inch² would be able to store a maximum of 125 GB per disk. IBM is already developing a similar technology: Pixie Dust technology currently achieves a data density of 25 GBit/inch².
