ABSTRACT:
A magnetic disk memory seats a memory disk with a consistent high accuracy by engagement on only one side of the disk with a drive chuck that imparts both a circumferential disk-rotating force and a radial disk-locating force. The two forces firmly seat an angled pair of precision disk faces onto the drive spindle.
The memory disk further can attach at only an inner periphery to the disk hub, by means of a selectively compliant adhesive tape, to allow the disk to deflect elastically away from the hub for accurate head penetration at inner recording tracks.
