Abstract:
A recording type decision device comprises optical irradiation means for applying an
optical beam to an optical type recording medium having an on-groove or in-groove recording
type and having a wobbled track, and tracking means for tracking an optical spot
formed by the applied optical beam so that the optical spot may be positioned on
the track. Further comprised are wobbled signal amplitude measuring means for
