1. A disk drive apparatus, comprising: a casing; a tray on which a disk-shaped recording medium or a disk cartridge having a disk-shaped recording medium stored therein is placed and/or which moves between a recording-and-playback position drawn inside the casing and a protruding position withdrawn outside the casing; at least one pickup disposed in the casing, recording information into and/or playing it back from the disk-shaped recording medium when the tray lies at the recording-and/or-playback position; and a chucking mechanism disposed in the casing, holding a chucked portion of the disk-shaped recording medium when the tray lies at the recording-and/or-playback position, the chucking mechanism comprising: a rotational driver disposed in the casing, rotationally driving the disk-shaped recording medium held by the chucking mechanism; an arm disposed to a portion of the casing above the tray lying at the recording-and/or-playback position so as to be vertically swingable, supporting and moving the attracted member between a retracting position retracting above the chucked portion and a chucking position at which the attracted member faces the chucked portion; and an arm-swinging mechanism which swings the arm so as to cause the attracted member to move to the retracting position when the tray moves from the recording-and/or-playback position to the protruding position and which swings the arm so as to cause the attracted member to move from the retracting position to the chucking position when the tray moves from the protruding position to the recording-and/or-playback position.
