  • Magnetic recording medium having a servo pattern of the intermittent type with compensation for suppressing self-generated residual fields
    Patent number: 5418670
    Abstract: A magnetic recording medium has recorded thereon a series of discrete time-limited servo signal bursts. To suppress residual fields emanating from each servo signal burst, at least one half-cycle of a compensating signal is recorded immediately prior to and immediately after each signal burst of a polarity opposite the polarity of the immediately adjacent half-cycle of the servo signal burst. Furthermore, each half-cycle of each compensating signal has a magnetic moment that is weaker than the magnetic moment of one half-cycle of the immediately adjacent servo signal burst.
