ABSTRACT:
A magnetic head slider having a high-pressure producing bottom surface which defines a path for passing compressed air streams produced by the rotation of a magnetic disc which flow between the magnetic head and the magnetic disc. The high pressure producing bottom surface is provided with pressure-reducing inclined grooves which separate a portion of the compressed air streams and guide them diagonally downstream to the outside.
