ABSTRACT:
A disk storage device, such as a magnetic disk storage device, for reading data from and writing data to a magnetic data storage disk includes a spindle onto a base for rotating the magnetic storage disk and a read/write head for reading data from and writing data to the magnetic storage disk. The read/write head is supported on a carriage which is movably mounted on the base for radially moving with respect to the spindle. A support plate is mounted on the carriage for retractably supporting the read/write head. An actuator mechanism actuates the support plate to move the read/write head between a nonretractable, operative position and a retracted, inoperative position. When the disk is not accessed by the read/write head, the read/write head is held in the retracted, inoperative position. Therefore, when the disk is replaced with another disk, the read/write head is prevented from being damaged or smeared with dust or dirt by contact with the disk.
