These developments give new-found mobility to users who were previously "plugged-in" to their desktops for the performance advantage. But users of the new Travelstar 7K60 mobile drive will not have to give up battery life for the additional speed. The new 7200 RPM drive offers power-consumption parity with its 5400 RPM counterpart, due to Hitachi's newly miniaturized femto slider.
The femto slider -- or the tiny flying wing supporting the read/write head A device that reads (senses) and writes (records) data on a magnetic disk or tape. For writing, the surface of the disk or tape is moved past the read/write head. By discharging electrical impulses at the appropriate times, bits are recorded as tiny, magnetized spots of positive or above the surface of the disk -- reduces power consumption and increases shock performance, adding to the overall superior mobile experience of the Travelstar 7K60. At 60 gigabytes (GB) of storage, the 7K60 is also the industry's most capacious ca·pa·cious

"The 7K60 changes the landscape for powerful mobility," said Bill Healy, general manager, Mobile Business Unit, Hitachi Global Storage Technologies. "With desktop-equivalent performance, the 7K60 represents the pinnacle of mobile hard drive innovation; it gives notebook manufacturers the key component they've been looking for Looking for

"Travelstar drives have been a staple component of the IBM ThinkPad line, and a consistent contributor to our leadership features and innovative mobile technology," said Peter Hortensius, general manager, Think products, IBM Personal Computing Refers to users working on their own computers rather than a terminal to a mainframe.

"Our customers demand the best technology, and Hitachi's new 7200 RPM notebook drive delivers, helping to continue the ThinkPad tradition of excellence."
Within the same family, Hitachi also announced today the Travelstar 5K80, which earns its rank among the Travelstar elite with the industry's highest performance and highest capacity at 5400 RPM. The 5K80 offers capacities ranging from 20 to 80 GB. IBM plans to incorporate the Travelstar 5K80 in several ThinkPad notebook models next month.
Nano, Pico, Femto
Hitachi underscores its mobile technology leadership with the industry's first implementation of the femto slider, which represents a 30-percent reduction in size over the previous-generation slider, called "pico." The new femto slider is less than 1 mm by 1 mm in dimension, which is roughly the size of the ball on a standard ballpoint pen.
"The tremendous revolution in hard disk drive storage technology over the past half century was led by miniaturization of every component in the system," said John Best, chief technologist, Hitachi Global Storage Technologies. "That trend continues with the introduction of the femto slider, which will enable significant improvements in manufacturing productivity, disk storage capacity and mechanical performance."
Hitachi's new femto slider significantly improves the following hard drive functions:
-- Reduces power consumption by 11 percent
-- Increases shock performance by 25 percent
-- Increases surface area available for recording by 3.5 percent
In addition, more efficient manufacturing can be achieved with the femto slider: when fully utilized, there can be up to a 65-percent increase in the number of femto sliders sliders

Hitachi Travelstar The Travelstar is a portable computer hard drive manufactured by Hitachi Global Storage Technologies. Models are available in 20GB to 250GB, 3600RPM to 7200RPM, 1.8" or 2.5", with PATA or SATA interface. External links
Until now, technical obstacles prevented 7200 RPM performance in a mobile hard drive. In the Travelstar 7K60, Hitachi overcame technical challenges associated with faster spinning drives without sacrificing any of the desirable attributes of leading-edge mobile drives: quiet acoustics acoustics (ək`stĭks) [Gr.,=the facts about hearing], the science of sound, including its production, propagation, and effects. , low power consumption, and excellent performance in high-vibration environments.
At 7200 RPM, the 7K60 spins 33 percent faster than its 5400 RPM counterpart, resulting in the following improvements:
-- Faster data transfer rate of 15 percent (rate at which data is
read and written)
-- Lower rotational latency rotational latency - The time for the start of the required sector on a disk to appear underneath the read/write head. The worst case is where it has just passed the head when the request is received. of 20 percent (time it takes disk to

The 7K60 also shows a 20-percent improvement in average seek time (time it takes the read/write arm to arrive at the desired data track).

HDD - hard disk drive category aimed at satisfying the needs of the most demanding mobile users. The Travelstar's new performance speed also helps to support an industry trend toward using notebooks as a desktop replacement.
5400 Performance, Capacity Leader
The Travelstar 5K80 offers the only 80 GB 5400 RPM mobile drive in the industry, boasting 30 percent more storage capacity than its closest competitor. In benchmark testing, the 5K80 performs, on average, 10 percent faster than competing 5400 RPM mobile drives currently on the market. The 5K80 has the lowest acoustics in a mobile drive and comes in 20, 40, 60 and 80 GB capacities. The 5K80 represents a combination of sophisticated hard disk drive design and technology leadership to support the notebook industry trend toward standardization on 5400 RPM performance.
Both the 5K80 and 7K60 are shipping in volume this month. Hitachi's new mobile drives complement the 4200 RPM Travelstar 80GN, shipped late last year, to offer customers the broadest portfolio of 2.5-inch mobile hard disk drive products on the market.
