Magnetic disk device without slider and having magnetic head mounted directly on magnetic head support including integral gas pressure generating structure

A magnetic disk device wherein magnetic head means reads information from a magnetic disk surface and writes information on the magnetic disk surface, said device comprising:

• an arm disposed at a distance from said magnetic disk surface;
• a magnetic head support including a single flexible member cantilevered to said arm, said single flexible member having a first end attached to said arm and having a second end extended toward said magnetic disk surface, said single flexible member having rigidity in a direction parallel to said magnetic disk surface and flexibility in a direction non-parallel to said magnetic disk surface over an area extending from said first end to said second end;
• at least one magnetic head provided on the second end of said magnetic head support;
• an actuator for rotating said arm so as to cause said at least one magnetic head to move toward or away from said magnetic disk surface;
• and
• gas pressure generating means for generating a gas pressure between said magnetic head support and said magnetic disk surface due to relative movement between said magnetic head support and said magnetic disk surface, said gas pressure generating means being integral with a portion of said single flexible member facing said magnetic disk surface.

A magnetic disk device wherein magnetic head means reads information from a magnetic disk surface and writes information on the magnetic disk surface, said device comprising:

• an arm disposed at a distance from said magnetic disk surface;
• a magnetic head support including
• a first magnetic head support including a single flexible member cantilevered to said arm, said single flexible member having a first end and a second end, said first end being attached to said arm, said single flexible member having rigidity in a direction parallel to said magnetic disk surface and flexibility in a direction non-parallel to said magnetic disk surface, and
• a plurality of independent second magnetic head support members provided on said second end of said single flexible member;
• a plurality of magnetic heads, each respectively provided on said second magnetic head support members;
• and
• gas pressure generating means for generating a gas pressure between said magnetic head support and aid magnetic disk surface due to relative movement between said magnetic head support and said magnetic disk surface, said gas pressure generating means being integral with portions of said second magnetic head support members facing said magnetic disk surface.
