摘要： A disk clamping mechanism for a disk driving device capable of simultaneously achieving disk centering operation for centering a disk inserted in the disk driving device and disk clamping operation for clamping the disk between a hub and a spindle head for driving the disk, through the swing motion of a door for closing the disk inlet of the disk driving device, comprising: a door plate 17 provided with the door at the free end thereof and urged toward the front of the disk driving device; a swing frame slidably supporting the door plate 17 and urged in the opening direction by spring means; an elastic clamping arm connected at the rear end thereof to the hub so as to press the hub against the spindle head with the disk clamped therebetween; and an adjusting screw screwed in the swing frame so as to be in abutment with the clamping arm 29 to press the clamping arm in the clamping direction when the door is closed by swinging the swing frame. The length of the projecting part of the adjusting screw projecting from the lower surface of the swing arm is adjusted so that the hub is pressed against the spindle head through the clamping arm at an appropriate pressure.

摘要： A disk recording and playback apparatus comprises a housing base, a cam body rotatably mounted on the housing base and actuatable in response to insertion of a magnetic disk, a bail mounted on the housing base and angularly movable toward and away from the housing base in response to actuation of the cam body, and a magnetic head mounted on the housing base and movable toward and away from an operative position in response to movement of the bail. When the magnetic disk is not inserted, the magnetic head is positioned away from the operative position by the bail disposed away from the housing base by the cam body, and when the disk is inserted, the cam body is actuated to release the bail to allow the magnetic head to be moved to the operative position.
