ABSTRACT:
A regenerating circuit is disclosed for use in a magnetic disc apparatus which uses a recording system to keep line density of each track in the recording media uniformly in each track. A low pass filter having a fixed cutoff frequency is used in combination with a wave equalization circuit in which time delay and gain are selected to provide a response which when combined with the response of the low pass filter results in an appropriate overall response for the zone from which the information to be processed originates.
