Abstract
A tape drive device includes a head member, a tape drive mechanism moving a tape, a suspension member supporting the head member, piezoelectric units, a drive voltage supply circuit applying a voltage to a piezoelectric element, and a controller. Each of the piezoelectric units includes a piezoelectric element. The controller determines a state of a head unit, based on a piezoelectric output generated at the piezoelectric element provided in the suspension member.
