ABSTRACT:
A lower magnetic head is attached to a carriage and a head support member supporting an upper magnetic head is hinged to the carriage. The head support member is provided on its lower surface in a continuous arrangement with a first flat portion, an inclined portion and a second flat portion. A cartridge holder for holding a disk cartridge, and a cross plate are fixed to an open upper end of a main chassis. A driving pin is fixed to the cross plate. When the carriage is moved away from a magnetic disk with an auxiliary chassis held at an upper loading position, the driving pin comes into contact wit the second flat portion of the head support member to separate the upper magnetic head from the magnetic disk. When the carriage moves toward the center of the magnetic disk, the driving pin is disengaged from the head support member, so that the upper magnetic head is pressed through the magnetic disk against the lower magnetic disk.
