Abstract

PURPOSE:To ensure to protect the disc and to perform stable information processing, by the constitution that the follower flange having the rotating shaft for disc drive is provided at the exterior of the enclosing case containing the disc and the drive flange is provided at the unit loading section. CONSTITUTION:In the enclosing case 10 of the disc unit 2, the disc 5 is in rotating- free contained, allowing to drive the disc 5 externally from the follower flange 13. On the other hand, the flange containing section 9 of the unit loading section 3 is provided with the drive flange 16 of the disc drive mechanism 4, and the disc unit 2 is set to the unit loading section 3 and the follower flange 13 and the drive flange 16 of the disc drive mechanism 4 are linked, allowing to deliver the driving torque and to rotate the disc 5. With this constitution, the contact of fingers on the disc 5 and the attachment of dusts can be avoided for stable information processing.
