Abstract
A tape drive for use with magnetic tapes includes a housing for receiving a magnetic tape having multiple parallel tracks, and a tape head for reading and writing the parallel tracks of the magnetic tape. A plurality of partial response maximum likelihood (PRML) equalization/detection channels are provided for processing the data signals to determine the data stream for each data signal. The plurality of PRML equalization/detection channels includes at least one PRML equalization/detection channel pre-assigned to each track. The plurality of PRML equalization/detection channels further includes at least one floating PRML equalization/detection channel dynamically assignable on an as-needed basis. The invention also contemplates an ASIC, a generic drive, and a PRML method.
