Abstract

PURPOSE: To realize fast access by providing fixed information for tracking on one of recording planes of an optical recording medium, and an optical pickup in which the recording plane different from another optical beam is irradiated with one of plural optical beams, and which performs tracking and the recording and reproduction of data with the optical beam.
CONSTITUTION: An optical recording medium D is equipped with a recording layer D1 on which a groove 1 as tracking information is formed, and a layer D2 superimposed on the layer D1 and possible to perform the recording and reproduction of the data 2 on two planes. The layer D1 is comprised similarly as the layer D2 so as to perform the recording and reproduction of the data 2 on the surface of the layer. Meanwhile, the optical beam of the optical pickup is provided with, for example, two beams LB1 and LB2 converged on the groove 1 of the layer D1 on the same optical axis and the boundary plane of the layers D1 and D2, and performs the tracking and the reproduction of the data 2 by capturing the reflected light of the beams. By using such optical recording medium D, it is possible to perform the recording and reproduction of the data 2 on the boundary plane of the second layer D2 as performing the tracking on the first layer D1 with the two optical beams LB1 and LB2.
