PHASE EQUALIZED READBACK APPARATUS AND METHODS ABSTRACT 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 read- back signal. In a preferred form, averaging phase errors over a predetermined signal characteristic of the readback signal controls adjustment of phase equalization.
