IBM Travelstar 40.0GB 4200 RPM 9.5MM Ultra DMA/ATA-5 IDE/EIDE

The innovative hard drive design combines AFC Media, Fluid Dynamic Bearing (FDB) motor technology, an ATA-100 interface, IBM 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 IBM storage technology - antiferromagnetically coupled (AFC) media, informally known as "pixie dust." This technology sandwiches 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 new IBM 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. In nontraditional applications, Travelstar drives can now incorporate into such products as Point-of-Sale Systems, Set-Top Boxes, Telemetry (automobile) applications, and communications and entertainment systems.
