    摘要： A recording/reproducing device suitably used in recording or reproducing data to/from an optical disk having two recording layers on one surface thereof, and a program. An optical disk having two layers on one surface one unformatted recording film (L0) layer and one formatted recording film (L1) layer, wherein the recording film (L0) layer is formatted by a mark in step S1, the formation of a mark corresponding to record data is started with the recording film (L0) layer first in step S2, and, after the recording film (L0) layer is used up, a mark corresponding to record data is formed on the recording film (L1) layer in step S3. This device can be applied to e.g. DVD players.

    摘要： An apparatus for reading optical card wherein a light source illuminates an optical card (1) so that data stored in an even number of tracks T in parallel with each other are optically read depending upon the arrangement of optical recording traces, the reflected light is allowed to fall on an optical detector element (10) to read the data, scanning means (31) so controls the light detector element (10) that it scans each track T an even number of times, effective scan detector means (42) detects effective scans capable of reading the data out of the even number of scans over the track T performed by the light detector element (10), and the output signal of the light detector element (10) is extracted for only a period of one scanning of the scanning means (31) by extract means (45) depending upon the detected output, whereby signals that correspond to the optical recording traces exhibits improved contrast, the two neighboring tracks are not read simultaneously, and recorded data are read correctly and stably.
