Rotation recording apparatus and method of inspection thereof

摘要

In addition to the conventional test pattern writing in a center of each track and inspection of burst patterns (A and B patterns) through a writing test in a SAT, there is also performed a test pattern data writing test, which is done at each boundary between tracks. With this additional test, it is possible to accurately inspect both C and D burst patterns that are sensitive to a PES signal at each boundary between tracks.
