Abstract
A data storage device includes a tape as a recording medium; a head member including a length larger than a width of the tape; and an electrical element expanding and contracting based on a polarity and an applied voltage. The head member is moved in a state where the voltage is applied and the electrical element expands or contracts.
Claims8
A data storage device comprising:
- a tape as a recording medium;
- a head member having a width and a length which is longer than the width, the head member comprising a first side portion and a second side portion each extending in the length direction of the head member;
- a first beam located on a side of the first side portion;
- a second beam located on a side of the second side portion;
- a first piezoelectric unit provided in contact with the first beam, the first piezoelectric unit comprising a first piezoelectric element which expands and contracts along the width direction of the head member thereby moving the first beam in a direction along a surface of the first beam;
- and
- a second piezoelectric unit provided in contact with the second beam, the second piezoelectric unit comprising a second piezoelectric element which expands and contracts along the width direction of the head member thereby moving the second beam in a direction along a surface of the second beam.
