Hitachi Travelstar 7K60 Hard Drives

Leading-edge technology

The Hitachi Travelstar 7K60 is a 9.5mm high, 7200 RPM, 2.5-inch mobile hard disk drive. The Travelstar 7K60 is the 28th generation addition of a long heritage of Travelstar mobile drives.

Designed with combined technology including; Antiferromagnetically-coupled (AFC) technology, Fluid Dynamic Bearing (FDB) motor technology, Giant Magnetoresistive (GMR) heads, load/unload head technology, Enhanced Adaptive Battery Life Extender (ABLE) 3.0 and an ATA/100 interface provides for a cutting-edge design. The Travelstar 7K60 pushes performance, capacity, power management, and exceptional quietness to provide a quality, high performance mobile hard disk drive for today’s demanding notebook and beyond systems.

New Areal DensityTechnology Advancements

Antiferromagnetically-coupled (AFC) media technology is incorporated into the Travelstar 7K60 to achieve an areal density of up to 50Gbits/sq.inch to be written on each disk. This feat is achieved by adding another layer or “pixie-dust” - or essentially an additional layer of 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 continuing to maintain data integrity.

One of the key contributors to achieving demanding areal density requirements has been the reduction of the size of the slider by 3x, and the mass of the slider by over 30x (from 1980 - 2002). Introducing the industry leading Femto Slider in the Travelstar 7K60, a reduced slider in both size and mass reduction. Hitachi GST is the first drive maker to incorporate the new Femto slider product in its hard disk drives.

Implementing the new Femto Slider has resulted in; improved shock resistance, reduced power consumption and improved disk storage capacity. The reduced slider size improves the response of the slider to disk waviness, thus reducing the flying height variation of the slider in the disk drive. These advantages coupled with an integrated slider suspension design, have been instrumental to achieving a 10x reduction in flying height over this same period.

Performance and reliability

The Hitachi Travelstar 7K60 series of hard disk drives utilizes proven storage technologies such as TrueTrack Servo, Drive Fitness Test (DFT), Self Monitoring Analysis and Reporting Technology (S.M.A.R.T.) to help maintain high performance and fast seek times at high environment temperatures.
