Abstract
An apparatus for correcting header information includes a transducer for reading and writing encoded information to a magnetic storage medium. A serial/deserializer provides a deserialized output. Header information from the deserializer is stored in a header storage register. The deserialized header information is also provided to a header error correction circuit. The header error correction circuit provides an output indicating location and value of errors in the header memory. This information is used to correct errors in the header memory. The corrected header information is compared with predetermined header information and used to determine whether subsequent data associated with the header should be written to or read from the magnetic storage medium.
