Title: Noise correction device
Inventor: HITOMI JUICHI
IPC: G11B20/06
Filed: 1989-10-06
Abstract: PURPOSE:To make a noise reducing effect much surer by performing displacement processing for correcting a noise near the zero crossing point of a correction signal. CONSTITUTION:A head switching pulse showing the switching timing of an A head and a B head and the correction signal which is an output from a noise correction circuit 15 are supplied to a switching pulse generation circuit 18. The switching pulse generation circuit 18 detects the zero crossing point of the correction signal, specifies the rising and falling of the head switching pulse by synchronizing with the detection timing and generates a new switching pulse.
