Abstract

PURPOSE:To stabilize revolution of a disc and to enable high density, by providing a support member having a plane opposing to a plurality of symmetrical points to the center of a disc via a fine gap and a drive means rotating the disc. CONSTITUTION:Support members 11, 12, 13 having a plane opposing to a plurality of symmetrical points to the center of a disc 1 via a fine gap 10, are provided and the support members are taken as a channel shape circular arc member surrounding an external circumference 14 of the disc 1. The drive means consists of a fine wind train 16 formed on an external circumference surface 15 of the disc 1 opposing to the members 11, 12, 13 and a fan mechanism delivering compressed air radial to the disc 1. Further, the fine wing train 16 is provided with a slope to the arrow 17 toward the delivery of compressed air.
