A high-area density is supported by progresses not only of BPI (Bits Per Inch) nowadays, but also of TPI (Tracks Per Inch). We proposed and approached new positioning mechanisms for HDD system. In this report, a linear actuator which was constructed with a linear air bearing and a voice coil motor was investigated. The actuator system is suitable for ultra-precise track following and high speed-seeking. This system had resonance frequency two times as high as a conventional rotary type. As the result of servo-tracking by using this actuator with D-MIG head, the tracking system can follow the track at precision within 1/20 track width of the head. Furthermore, the actuator can feed at 10 nm resolution and keep constant speed by using an optical fiber displacement sensor.
