Toshiba has developed a hard disc drive for notebook computers that can hold 100Gbytes of data. The company expects to begin selling it later this year.
The drive offers a quarter more storage space than the company's highest capacity notebook drive and is the first 2.5-inch drive from any manufacturer to store 100Gbytes, Toshiba claimed.
The company employed a new thin-film technology on both the head and platter to make the drive, which increased the head's sensitivity and allowed engineers to increase the areal density.
Toshiba also changed the slider that keeps the drive's read/write head at the correct distance above the disc surface. The slider is 35% smaller and much lighter than the old one. Its reduced size means the head assembly can get closer to the outer edge of each platter, freeing up more space for data storage.
The drive contains two 2.5-inch platters to bring the total capacity to 100Gbytes.
Operating shock resistance has also been increased to 325G, which is 50% higher than Toshiba's 80Gbyte drive, and power consumption is 20% lower on average.
The drive has an ATA-6 interface and speed of 4,200 rpm. Toshiba will begin sample production of the new drive in May and expected commercial production to start during the third quarter of this year.
