PHASE EQUALIZED READBACK APPARATUS AND METHODS

摘要

PHASE EQUALIZED READBACK APPARATUS AND METHODS A magnetic recorder employs a feedback phase equalizer for adjusting the readback signal to enhance detection capability. Phase errors are measured and used as criteria for dynamically and adaptively adjusting phase compensation of the readback signal. In a preferred form, averaging phase errors over a predetermined signal characteristic of the readback signal controls adjustment of phase equalization.
