摘要：
The sector formats of adjacent record tracks are made different from each other so that a region of an ID signal of a header part of one of the record tracks is adjacent to a region (VFO part) other than an ID signal of a header part of the other record track and the regions of ID signals are not adjacent to each other. A crosstalk component from the VFO part which is the closest pattern is so small that it little affects the reproduction of an ID signal. Therefore, an ID signal is correctly reproduced.
