A memory area) section 4, a lead-in section 5, a Program section 6, and a lead-out section 7 are provided. A guide groove is formed on the recording track of the CD-R. This guide groove is 22.05K.
Wobbling is formed by a signal of a frequency obtained by FM-modulating a carrier wave of Hz with data indicating absolute time information. The laser beam controls tracking along the guide groove, and the center frequency of the wobbling signal is 22.05K.
By controlling the rotation speed of the spindle motor so that the frequency becomes Hz, tracking control and spindle control can be performed even on an unrecorded optical disc. PCA3
In order to properly adjust the laser output during recording,
An area in which trial recording is performed prior to recording,
The A3 section is composed of test blocks divided into a plurality of areas, and one test recording consumes one of the test blocks. The area of the test block once test recorded cannot be used for the next test recording, so
The unused test block is searched, and the trial recording is performed every time the CD-R is mounted in the optical disk recording device. PM
The A section 4 is an area for recording the management information of the information signal recorded in the program section 6, and the start address and end address of the track number for the information signal recorded in the program section 6 are recorded therein.

きる。Since the write-once type optical disc is often supplied in a bare state, it is recorded in a state where the optical disc is recorded, for example, the disc is finalized and cannot be additionally recorded, or is in a state before finalization. If there is, or if it is possible to write additionally, what percentage of the remaining recording capacity cannot be determined unless the target optical disc is reproduced and the data is read from the optical disc. In addition, it takes about several minutes to set up the optical disc in a reproducible state, which is inconvenient. According to this embodiment, the recording state of the above-mentioned optical disc can be determined without reproducing the optical disc.

In the state of%, the recording condition of the disc, for example, a numerical description of the remaining recording space capacity, or a notation that additional recording is possible, that is, notation that finalization processing is not performed, is written in the character index column such as the back of the disc of the optical disc. It is difficult to write and erase easily with a general-purpose writing instrument. In this embodiment, the fact that the reflectance of the recorded portion and the unrecorded portion of the recording surface of the optical disc can be visually discriminated is utilized. The present invention is not limited to the data recording operation on the optical disk, but is formed on the optical disk as a visible marking by utilizing the phenomenon of different reflectances.

A finalize instruction is not input in the replenishment recording such as the track-at-once recording or the packet write recording. The recording operation in this case is as follows:
Starting from the third area of the optical disc. In the conventional optical disc, recording is performed from the second area of the optical disc.
In this embodiment, the head sector number is recorded in the PMA section so that recording can be performed from the track number and sector corresponding to the third area. Subsequently, the servo unit 19 controls the laser unit unit 13 so as to position the seek actuator mechanism 12 and the seek actuator 11 so as to correspond to the optical disc radius of the sector, and performs recording on the optical disc by the above-described recording operation. The most characteristic feature of the above operation is that recording is performed from the third area without recording the second area.
