摘要

A recording head Hw1 records a record signal including a data region, a pilot signal region, and a mask region with a width of 3 Tp. A recording head Hw2 overwrites the record region of the head Hw1 with another data. Since the recorded signal includes the mask region, the pilot signal region recorded by the head Hw1 is not erased. The recording head Hw1 overwrites with a record signal. At this point, since the recorded signal contains a mask region, the former pilot signal region is not erased. Instead, a new pilot signal region is formed. By repeating these operations, pilot signal regions are adjacently formed at track edges of a track corresponding to the recording head Hw1. Since the pilot signal is reproduced by a reproducing head with the same azimuth as the recording head, the pilot signal with a short wavelength can be used.
