Hitachi Travelstar 40GN IC25N020ATCS04 - hard drive - 20 GB - ATA-100
Mobile storage leadership continues with the Hitachi Travelstar 40GN hard drives. The innovative hard drive design combines AFC Media, Fluid Dynamic Bearing (FDB) motor technology, an ATA-100 interface, giant magnetoresistive (GMR) head technology, Partial Response Maximum Likelihood (PRML) digital channel, a head load/unload feature, and Enhanced Adaptive Battery Life Extender (ABLE) 3.0. This design provides the exceptional quietness, storage capacity, performance, power management, quality, and reliability required by today's notebook systems. The Travelstar family of hard disk drives incorporates the latest storage technology - Antiferromagnetically-coupled (AFC) media, informally known as "pixie dust". This technology sandwiches a three-atom-thick layer of ruthenium, a precious metal, between two magnetic layers on a disk, allowing for a higher areal density, breaking through limitations of the super paramagnetic effect. 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.
