Abstract
A disk drive apparatus for recording and reproducing desired information on and from floppy disks, is simply and thinly structured and has an excellent shock resistance. The disk unit includes a support for carrying a pair of heads for pinching a magnetic disk from both sides thereof and for reading and writing information thereon supported on respective carriages that can move the pair of heads to a desired track on the disk, and a holder, supported by the support, for storing a disk cartridge. The holder is provided with a head guard movable between a guarding position where the head guard is inserted between the pair of heads to prevent the pair of heads from abutting each other and a withdrawn position where the head guard is withdrawn from between the pair of heads, and a spring for urging and moving the head guard to the guarding position. The head guard moves from the guarding position to the withdrawn position when one end of the disk cartridge to be stored in the holder abuts with a part of the head guard.
