Abstract
A storage device includes a substrate, a magnetic storage medium provided on the substrate, information being magnetically stored in the magnetic storage medium, a head unit, and a reciprocating mechanism provided on the substrate, the reciprocating mechanism causing the head unit to reciprocate in a plane parallel to a surface of the magnetic storage medium, wherein, while the head unit is being moved by the reciprocating mechanism, information is recorded in or reproduced from the magnetic storage medium via the head unit. The reciprocating motion of the head unit is provided by piezoelectric elements on arms supporting the head, which move the head with a predetermined stroke width in simple harmonic motion.
