摘要： PURPOSE: To obtain an information recording medium having excellent safety and a high forgery preventive effect without effecting the recording and reproducing of the information by providing a protective substrate and a printing layer with stamped information. CONSTITUTION: The information recording medium is constituted by sticking an optical recording layer 13 disposed on a transparent substrate 14 via an adhesive layer 12 to a protective substrate 11, providing the surface of the protective substrate 11 with the printing layer 15 and providing the protective substrates 11 and the printing layer 15 with the stamped information 16 which is simultaneously stamped. The stamped information 16 is not peeled like a seal and is not limited in the kind and installation method of initializing information to be disposed on the printing layer 15. Further, this information forms the non-changeable reggedness on the card but the deformation does not reach the transparent substrate 11 and, therefore, the optical recording and reproducing of the card are not affected. Thereby, excellent safety is obtd. and the forgery preventive effect is enhanced.

摘要： PURPOSE: To improve the reliability of information already recorded by storing the information of the block existing adjacent to the block which records information in a buffer inside the information recording and reproducing device. CONSTITUTION: The above device 14 is composed from an MPU 6, a modulating/ demodulating circuit 5, a semiconductor laser driving device 9, and an AT/AF control circuit 9 which conducts auto tracking control and auto focussing control. An interface 2 which controls the device 14 by the commands from the host computer 1 is provided with a buffer RAM 3 which stores recording and reproducing information in it. The reliability at the time of recording and reproducing information is improved by storing the information on the final recording position (EOT) which is Track-1 track to be recorded with new information and the EOT+1 track into the recording information storing region inside the buffer RAM 3.

摘要： PURPOSE: To represent reproduced data having contents that are hardly represented by a printer by the data reproduction system which reproduces codes. CONSTITUTION: A data discrimination device 31 of a data reproduction device 3 discriminates the contents of data decoded by subsets through a dot reader 2 and a printer controller controls a printer device according to the discrimination result to print out data. In this case, the printer controller 32 previously stores an adequate printing method according to the discrimination result of the data discriminating device 31 and when the corresponding discrimination result is inputted, a control information generation device 32A outputs printer control information by the printing method; and a data processor 32B processes and outputs the data.

摘要： PURPOSE: To prevent the generation of lowering of light quantity and deterioration of a spot shape and to enable excellent and stable recording/reproduction by making a P-polarizing light beam incident on a total reflection optical element having a reflection surface whose outer face is fitted with a protection film. CONSTITUTION: A P-polarizing light beam by a semiconductor laser 1 is made incident on a parallel shift prism 18 of a total reflection element having a total reflection surface fitted with a protection film, reflected by the total reflection surface, made incident on a movable head part 10 and a disk, etc., irradiate them. By this constitution. The deterioration of the characteristic of the total reflection surface of the prism due to the secular change, etc., is prevented by the protection film, the decrease of the light quantity and the deterioration of the shape of a light spot are prevented since the P-polarization is utilized and stable and excellent recording/reproduction is performed.

摘要： PURPOSE: To improve transfer efficiency of the data and to miniaturize and thin a pickup device by setting a length of a line segment linking a center of an objective lens with the center of a rotary drum provided in a rotary optical part in the length prescribed by the length in the long side direction of an optical card recording surface and 1+cos(θ/2). CONSTITUTION: Reflection mirrors 19, 20 and the objective lens 21 leading a light beam outgoing from a fixed optical part SOP to the recording surface of the optical card 24 are placed on the rotary drum 22 of the rotary optical part ROP, and the rotary motor 23 of the rotary drum 22 is arranged also. At this time, by setting the length of the line segment linking the center of the objective lens 21 with the center of the rotary drum 22 based on the length in the long side direction of the optical card recording surface and 1+cos(θ/2), an optimum rotational radius for the size of the optical card is obtained.
