本発明は光を用いて記録、再生または消去を行う光学式
記録媒体において、光学式記録媒体の種類を識別するた
めのマークを、記憶領域以外の部分に設けたことを特徴
とする。(Means for Solving the Problems) The present invention provides a mark for identifying the type of optical recording medium in an area other than the storage area in an optical recording medium that performs recording, reproduction, or erasing using light. It is characterized by having been provided.
以下、本発明を実施例に基づいて詳細に説明する。 Hereinafter, the present invention will be explained in detail based on examples.

マークとマーク以外の部分の光の反射率に差があるほど
センナでの検出が容易になるので、例えばラベルの色が
白ならばマークの色は黒というようにする。FIG. 1 shows an example of a location where an identification mark is provided in an optical recording medium of the present invention. 1 is the storage 9α area, 2 is a label, and 3 is a mark for identifying the type of medium. In this example, three glands are used for the identification mark; for example, one gland is used for read-only media, two glands are used for write-once media, and i! 7 If the medium is replaceable, there are three lines, and the number of lines can be changed depending on the type of medium. Also,
The greater the difference in light reflectance between the mark and the parts other than the mark, the easier it is to detect with the sensor, so if the label color is white, the mark color should be black, for example.

て簡単に設けることができる。FIG. 2 is a diagram showing an example of how to provide an identification mark. In (a), a strip-shaped mark is provided and the number is detected by a sensor, and in (b), the shape of the mark is circular. In (C), the type of medium is identified not by the number of marks as in (a) and (b), but by the difference in length. The shape and number of the identification marks can be changed as long as they are within the range that can be detected by the sensor for detecting the marks. Also, the mark can be easily provided by printing it directly on the label or pasting it in the form of a sticker.

。FIG. 3 is a diagram 11-y of one embodiment of a device for detecting an identification mark provided on an optical storage medium of the present invention. 4 is an optical recording medium; 5 is a sensor for detecting an identification mark; 6 is a detection circuit that generates a detection signal using a signal from the sensor; 7 is an optical recording medium that uses a signal from the detection circuit; 8 is a control circuit that controls the drive of the optical recording medium. For the sensor No. 5, for example, if a photo ink converter with a built-in infrared light emitting diode and a phototransistor is used, the boat will be small and light, and the detection circuit will be simple. It should be noted that the embodiment mentioned here is just one embodiment.
