Publication number: 20040255310Abstract: A disk drive apparatus includes a casing having an upper plate; and a tray. The upper plate includes an arm having an attracted member fixed thereto. When the tray moves from a protruding position to a recording-and-playback position, since engagements of the arm and the tray are engaged with each other, the main body of the arm swings, and the attracted member serves as a chucking position facing a chucked portion of the disk-shaped recording medium placed on the tray. When the tray moves from the recording-and-playback position to the protruding position, since the engagement of the arm is detached from the engagement of the tray, the main body of the arm swings, and the attracted member serves as a retracting position retracting above the chucked portion of the disk-shaped recording medium.Type: ApplicationFiled: April 5, 2004Publication date: December 16, 2004Inventors: Manabu Obata, Mitsunori Matsumura, Zensaku Mitsuji, Hideaki Tsutsumi, Hisashi Negoro
