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

摘要

A magnetic disk device includes an arm disposed at a distance from a magnetic disk surface, a magnetic head support having a first end associated with the arm and having a second end extended toward the magnetic disk surface, a magnetic head provided on the second end of the magnetic head support, and an actuator for rotating the arm so as to cause the magnetic head to move toward or away from the magnetic disk surface. The magnetic head support has rigidity in a direction parallel to the magnetic disk surface and flexibility in a direction non-parallel to the magnetic disk surface over an area extending from the first end to the second end of the magnetic head support, and includes a gas pressure generating structure integral with a portion of the magnetic head support facing the magnetic disk surface for generating a gas pressure between the magnetic head support and the magnetic disk surface due to relative movement between the magnetic head support and the magnetic disk surface.
