摘要： There is provided an optical information recording/reproducing device for recording, reproducing, or erasing information on an optical information recording medium including information tracks formed on a disk substrate including alternating groove tracks and land tracks each including: a header region for recording identification data representing location information in pre-pits; and a data region for recording user data, the pre-pits being grouped into blocks, the blocks wobbling alternately toward an inner periphery or an outer periphery of the disk substrate along a radius direction from a center line of each information track by a distance which is substantially 1/2 of the information track pitch. The pre-pits are provided along the radius direction at a pitch twice as large as the track pitch. The device includes: an optical system for radiating a light beam as a converged beam spot on an information track; an optical detector including two light receiving portions divided in parallel to the track direction for receiving the light beam reflected from the recording medium; a signal generator for generating a differential signal and an addition signal of output signals respectively output from the light receiving portions; a header region detection circuit for determining whether the converged beam spot is tracing the header region or the data region using the differential signal; and at least one reading circuit for reading the identification data from the differential signal and for reading information recorded in the data region from the addition signal.
