Record manner and tracking error detection device null of signal for tracking error detection

摘要

PURPOSE: To obtain a high-accurate tracking error signal by nearly coinciding the start and end position of the first and second detection gate signals and the first and second integrated gate signal respectively to the center of the pulse width of the first and second tracking error detection burst pulse signals. ;CONSTITUTION: The first and second tracking error detection burst pulse signals are supplied to a full-wave rectification detection circuit 6, thereby the first and second detection gate signal DG is obtained from a servo system processing circuit 10. The detection output is supplied to an integrator 7, thereby the first and second integrated gate signal IG is obtained from a servo processing circuit 10. The first and second tracking error detection burst pulse signals are recorded on a magnetic disk 1 so that the start and end positions of first and second detection gate signals and that of the first and second integrated gate signals are to be nearly coincided to the center of the pulse width of the first and second tracking error detection burst pulse signals.;COPYRIGHT: (C)1993,JPO&Japio
