New TECHNOLOGY exceeds expectations

Travelstar™ 5K160, Hitachi’s first hard drive to use perpendicular magnetic recording (PMR), delivers superior TECHNOLOGY and reliability. With capacities up to 160 GB, industry-leading performance, low-power consumption and excellent shock resistance, Travelstar 5K160 has the key attributes to support the stringent demands of portable computing. Improved electronics design further reduces the power consumption of this 5400 RPM drive, which beats its industry-leading predecessor by 10%; the 5K160 also runs cooler than the competition. Hitachi has also implemented Thermal Fly-height Control (TFC) for improved error rates, and iridium-manganese-chromium (IrMnCr) read heads for improved reliability. Hitachi has done extensive testing to verify Travelstar 5K160‘s best-in-class standing, making it the “Super-pendicular Drive.”

Reliability leadership

With the transition to new PMR technology, Travelstar 5K160 demonstrates reliability that parallels or exceeds 50-year old conventional longitudinal technology. Hitachi has integrated second-generation PMR head and media technology, along with a new read channel and IrMnCr read heads. This successful transition required new materials, complex processes, tools and testing. Hitachi LEVERAGED the depth and breadth of its internal resources to deliver the most reliable PMR mobile product in the industry.
