Fujitsu's U.S. subsidiary Aug. 30 introduced two new mobile hard disk drives with perpendicular magnetic recording—a feature that lets a disk greatly increase its capacity for data. The two new additions—the first mobile disks with PMR in Fujitsu's product line—are the MHW2160BH series, a 160GB, 2.5-inch SATA (Serial ATA) model featuring PMR technology; and the MHW2080AT series, an up-to-80GB PATA (Parallel ATA) hard disk drive.
The 160GB SATA product was developed to address customer demand for increased storage capacity, while the 80GB disk drive was designed for the consumer electronics and external USB storage markets, a company spokesperson said. Perpendicular magnetic recording is a newly implemented technology for data recording on hard disks that was first demonstrated in Japan in 1976. The technique is believed to be capable of delivering up to 10 times the storage density of conventional longitudinal recording—on the same media.
