ABSTRACT:
A disk drive with a turntable for supporting a flexible magnetic disk thereon has a spindle extending centrally through the turntable for engaging a first opening formed centrally in a sheet metal hub of the disk, and a drive pin arranged eccentrically of the turntable for driving the disk by engaging a second opening formed eccentrically in the disk hub. The drive pin support is made of a sheet metal support of resilient material and has an arcuate shape which is mounted flat to an underside of the turntable for deflection in a plan normal to that of the turntable. In view of the reduction of the space required for the deflection of the drive pin support and the total thickness or height of the disk drive, the drive pin is erected on an offset head portion of the support. The offset head portion together with the drive pin there-on is received in a clearance opening in the turntable so that a less space is required for the deflection of the drive pin support between the turntable and an underlying part such as a stator of a disk drive motor than that in the prior art.
