ABSTRACT:
A piezo actuator is provided between a suspension spring and a head carriage. When a predetermined track of a magnetic disk is accessed by positioning a magnetic head in the predetermined track, the piezo actuator maintains the magnetic head in an ON track state by dynamically moving a light weight head cartridge according to a servo information or dynamically moving a head assembly in the head cartridge according the servo information.
