  • Patent number: 5835474
    Abstract: A disk device includes a chassis, a replay unit for supporting a disk placed within the chassis, rotating the disk, and reading data from the rotating disk, a vibration-isolating unit for holding the replay unit by connecting the replay unit to the chassis and for isolating the replay unit from vibrations, a carrying unit for carrying the disk between a disk inlet and outlet formed on the chassis and a replay position where the disk is to be fixed in the replay unit, a motor for driving the carrying unit, and a flexible printed circuit (FPC). The FPC is mounted to one lateral surface of the motor and is electrically connected to the motor. The FPC has a projecting portion which projects from an upper surface of the motor toward one surface of the disk fixed in the replay unit. The projecting portion of the FPC is adapted to be brought into contact with the disk to prevent the disk from coming into contact with the motor when the disk moves closer to the motor.
