Abstract

PURPOSE:To make correct tracking possible and make it possible that an optical recording card meets various hard conditions of various kinds of device, by forming a row of information pits and a cottony optical recording area for tracking, which is formed by optical recording, alternately on an optical recording material film. CONSTITUTION:Optical recording areas 14 for tracking are formed at intervals on an optical recording layer 13. Optical recording areas 14 are recorded optically into stripes on the optical recording layer 13 by the irradiation of a laser beam similarly to formation of recording pits. Rows of information pits 15 are formed between optical recording areas 14. In case of read, the spot of a laser beam for read uses optical recording areas 14 as a guide to track information pits 15. Since optical recording areas 14 are formed when the card is issued, intervals of optical recording areas 14 and the number of them are determined in accordance with demand even if contents of recorded information are different by the owner of the card and issuing persons are various, and the pitch of rows of information pits is reduced as much as possible as long as hard conditions of a device permit.

Recording 4AII uses Cal71 glid glass, etc., and utilizes the phase transition of Amorphno-Su 3 crystals,
Magneto-optical recording using polycrystals such as Ml13i and amorphous materials such as GrIco is known. In the case of optical recording on this, a spot of light U' L = -IJ' is irradiated onto the film of the optical recording material according to the digital signal from the writing head (original information). In addition, when reading the information recorded in this way, the read head illuminates the film of the optical recording material 1"-beam, and the anti-Q. The information bits are detected by light, and when reading out the digital signals, the readout beam (Arpem's Spora 1) accurately trunks the columns of information bins 1 and 7.
For this purpose, in the past, for example, three-beam Rayleigh beams were used (the three-beam method), and tracking was performed correctly from the difference in the output of the anti-nj light of each beam. Although it has been developed to detect whether or not there is a target and correct the trajectory, this method is not necessarily suitable for high-speed tracking.

rl (Depending on the hardware conditions of the loading device and the reading device, it is possible to reduce the pitch of the information pin 1-row and form a large number of information pins 1 to r11 to store a large amount of information in the optical recording layer. Despite this, there remains the drawback that the amount of information is limited by the number of racking grooves, which is a constraint on recording information specific to the optical recording card holder and the sender fj, and The optical recording devices that can be used by optical recording card issuers are also limited to specific ones.
Optical recording cards cannot be provided with versatility, making it difficult to quickly issue individual ID cards and the like. Furthermore, conventionally, when forming grooves for 1-shoes and 1-rings, three master plates 2 of 1 to 2 for racking were prepared using nickel electroforming (see Fig. 1), and this master plate 2 is used as a stamper to form a racking groove 4 on a plastic molded substrate 3, and then a film 5 of an optical recording material is formed on the entire surface of the substrate 3 by means of vapor deposition or the like.
Therefore, in addition to inputting and outputting the information bits, another process is required to form one disk for one racking, which makes manufacturing one culm of the optical recording medium 1 complicated and increases the price. It becomes.
