摘要
A magnetic memory disk drive apparatus with reduced R.F. noise includes a d.c. drive motor. The disk is coupled to the motor shaft by a drive plate and a drive plate hub which have surfaces interleaved with a grounded housing to provide a shunt capacitance which reduces the noise signal produced by commutation reaching the magnetic disk.
