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. To increase the throughput of the read channel, multiple sample values are processed in parallel. In the example embodiment disclosed herein, two sample values are processed in parallel.
