MECHANISM FOR SUPPORTING HEAD OF DISK DEVICE AND THIN FILM PIEZOELECTRIC BODY ACTUATOR

摘要

PROBLEM TO BE SOLVED: To highly precisely and efficiently micro-displace a head for correcting tracking or the like. SOLUTION: A slider 2 equipped with a head 1 for operating at least data reproduction to a disk to be rotated is arranged across full azimuths in a micro- rotatable state. Each side part of the slider 2 is supported on each edge part of a pair of wiring board parts 8d and 8e arranged in a mutually parallel state. In this case, thin film piezoelectric bodies 11a and 11b are respectively mounted on each wiring board part 8d and 8e along each wiring board part 8d and 8e, and when a voltage is respectively applied to each thin film piezoelectric body 11a and 11b, each thin film piezoelectric body 11a and 11b is expanded and contracted along each wiring board part 8d and 8e, and each wiring board part 8d and 8e is turned into a bent state so that each side part of the slider 2 can be displaced.
