A floating head and information recording and reproducing apparatus for accessing a zone texture medium

摘要

The head is provided adjacent to the CSS zone 2 of the recording medium 1 and includes first air bearing surfaces 131 and 132 that extend in the direction of rotation A of the medium when the head 113, . The first air bearing surface floats above the set flush height for the CSS zone when the medium is rotated and the head accesses the data zone 3 of the medium. The second air bearing surface 131, 132 is provided spaced apart from the CSS zone and extends parallel to the first air bearing surface when the head is facing the medium 1. When the medium is rotated and the head accesses the data zone, the second air bearing surface floats above the set flush height for the data zone. So that the head is tilted about a horizontal axis parallel to the rotation direction A to avoid contact with the medium when the head accesses the data zone 3 of the closest region to the CSS zone 2, The second air bearing surfaces 131, 132, 133 are provided in an asymmetrical arrangement.
