Test recording method and optical information recording/reproducing apparatus for determining an optimum power of the light output from a light source in erasing pieces of information recorded on a land and groove of a recording medium
A test recording method is provided to determine an optimum power of a light output from a light source in erasing pieces of information recorded on a land and a groove of a recording medium. A predetermined signal is recorded on a predetermined track of the medium. Data on a track adjacent to the track where the signal is recorded is erased with different erasing powers. The signal recorded on the track is reproduced to detect a reproduction signal. An optimum erasing power is set on the basis of the reproduction signal and the different erasing powers.
