ABSTRACT:
A data storage apparatus has a magnetic head opposed to a magnetic recording medium and movable relative to the medium so as to magnetically write or read data to or from the medium. A displacement sensor monitors a distance between the head and the medium. An actuator which supports the head is driven according to the monitored results so as to maintain constantly the distance. The actuator includes a vibrator for vibrating the head at a given frequency effective to produce air pressure against the medium. The head has a bottom face opposed to the medium and convexed outwardly toward the medium, and the medium is made of elastic material concavedly deformable in response to the air pressure.
