Manufacturer's product description
The Hitachi Travelstar 80GN is a 9.5mm high, 4200 rpm, 2.5-inch mobile hard disk drive. The Travelstar 80GN brings a 26th generation addition to the long line of Travelstar family drives. The innovative hard drive design combines AFC Media, Fluid Dynamic Bearing (FDB) motor technology, Giant Magnetoresistive (GMR) heads, Partial Response Maximum Likelihood (PRML) digital channel, head load/unload technology, Enhanced Adaptive Batter Life Extender (ABLE) 3.0, and an ATA/100 interface. With this design, the Travelstar 80GN provides exceptional quietness, storage capacity, performance, power management and quality required by today's demanding notebook systems. The Travelstar 80GN breaks current areal density records by allowing up to 70Gbits/ per square inch to be written on each disk. This was achieved by adding another coating of "Pixie Dust" - or an additional ruthenium/magnetic layer to create a five-layer sandwich called laminated-"Pixie Dust". These additional layers bring even higher thermal stability to the media, allowing data recording at ultra-high densities while maintaining data-integrity. As a result, the Hitachi Travelstar drives are suitable for demanding, high-capacity Internet, digital audio, video streaming, and real-time multimedia applications - whether users are in the office or on the road.
