Title: Read circuit for magnetic disk device
Inventor: OMORI SUSUMU
IPC: G11B5/09
Filed: 1989-05-15
Abstract: PURPOSE:To normalize a read pulse even when a false signal is included in a readout signal by generating a read pulse signal by comparing a peak detection signal from which a signal with a prescribed frequency is eliminated with the differential signal of the readout signal. CONSTITUTION:A pulse signal E is outputted when the input level of a terminal A exceeds that of a terminal B at a comparator 15. The signal is converted to a pulse signal Ea with time width set at a monostable multivibrator 31, and a false pulse included in the signal E is neglected. Next, it is supplied to a monostable multivibrator 32, and is converted to a pulse signal Eb with the same pulse width as that of the signal E. The signal Eb is inputted to the terminal Ck of an FF 16, and a pulse signal Dp from a differentiation/delay circuit 21 is latched with the FF 16, and the read pulse signal corresponding to the readout signal Rs and also, from which the false signal is eliminated can be generated via a data generation circuit 22.
