ABSTRACT:
A synchronous read channel is disclosed which samples an analog read signal from a magnetic read head positioned over a magnetic disk medium, filters the sample values according to a desired partial response, extracts timing information from the filtered sample values, and detects an estimated data sequence from the filtered sample values using a discrete time sequence detector. The read channel further employs an error tolerant sync mark detector, as well as a sync mark recovery procedure for synchronizing to the data when the sync mark is destroyed by a defect.
