Title: Magnetic disk unit
Inventor: KURIHARA HARUYUKI
IPC: G11B21/12
Filed: 1990-11-22
Abstract: PURPOSE:To avoid that a magnetic head collides with a magnetic disk by installing a holding means by which a support member supports a suspension and which separates the magnetic head from the face of the magnetic disk when this unit is not actuated. CONSTITUTION:When a unit whose magnetic disk 5 has stopped turning is not actuated, a suspension 9 is lifted up by the tip part of a buffer material 25, and a magnetic head 7 is supported in a state that it is separated from the magnetic disk 5. When, in this state, a shock or a vibration is exerted on the unit in such a way that a force acts in a direction in which, e.g. the magnetic head 7 is advanced to the face of the magnetic disk 5, the shock or the vibration is received by the buffer material 25 via the suspension 9. The buffer material 25 regulates the displacement of the magnetic head 7; it is deformed elastically and absorbs the shock. When the magnetic disk 5 starts turning, an air current acts on a blade part 27, and the buffer material 25 is turned against the turning effort of a shaft 21 and releases the support to the suspension 9. Thereby, it is possible to avoid that the magnetic head collides with the magnetic disk and to prevent both from being damaged.
