with the data itself. According to Appellant, by including these
periodic reference bytes, in addition to synchronization and
timing bytes that are typically included at the beginning of a
data sector, the system can continually update and/or adjust its
phase control and gain control as needed (specification, page 3).
An understanding of the invention can be derived from a reading
of exemplary independent claim 1, which is reproduced as follows:
1. A method of storing data on a storage medium having data
storage areas and retrieving the stored data which includes the
ability to predict readout errors when the stored data is
retrieved, comprising:
interleaving the data with a plurality of reference
fields, each reference field including a defined data
pattern;
storing the interleaved data within the data storage
areas such that the reference fields are at predetermined
locations;
upon demand, retrieving the interleaved data;
analyzing the retrieved interleaved data by testing the
retrieved reference field to determine if the retrieved
reference field meets a predetermined shape condition and a
predetermined amplitude condition; and
determining whether readout errors have been
encountered based upon the results of the interleaved data
analysis.
