A head includes a first air bearing surface (131, 132) which is provided adjacent to a contact-start-stop zone (2) of a storage medium (1) and extends in a rotational direction (A) of the medium when the head (113, 200, 250) confronts the medium. The first air bearing surface is levitated above a given levitational height for the contact-start-stop zone when the medium is rotated and the head accesses a data zone (3) of the medium. A second air bearing surface (131, 133) is provided apart from the contact-start-stop zone and extends parallel to the first air bearing surface when the head confronts the medium (1). The second air bearing surface is levitated above a given levitational height for the data zone when the medium is rotated and the head accesses the data zone. The first and the second air bearing surfaces (131, 132, 133) are provided in an asymmetric configuration such that the head (113, 200, 250) is held in an inclined condition around a horizontal axis parallel to the rotational direction (A) to avoid contact with the medium when the head accesses a nearest area of the data zone (3) to the contact-start-stop zone (2). <IMAGE> |
