ABSTRACT:
A head loading mechanism of a disk apparatus includes an arm for holding a magnetic head at a leading edge of the arm, the arm longitudinally extending in a radial direction of a magneto-optical disk toward the center of the disk and having a base portion and a plurality of laterally projecting portions between the leading edge and the base portion, a first supporting part for supporting the base portion of the arm, a second supporting part for supporting the laterally projecting portions of the arm when the disk is placed in a read/write position where information is recorded on or reproduced from the disk, and an arm raising part for vertically rotating the arm around the base portion supported by the first supporting part when the disk is moved from the read/write position to an insertion position, allowing the magnetic head to be placed in an unloaded position in which the magnetic head is separate from the disk.
