摘要： PURPOSE:To easily record and reproduce information at high density by the characteristics of an org. material relating to the optical recording medium which records and reproduces the information by using the light generated by storage media. CONSTITUTION:Disk-or card-shaped optical memory media 1, 41 are constituted of a photo-thermal conversion part 2, an optical change part 3 mixed with org. material particles 4, and a protective film 7 which allows the transmission of, for example, only the IR rays. Heat is generated in the photo-thermal conversion part 2 by the irradiation of the prescribed intensity from a light source 8 and the optical change part 3 is changed proportionally in optical characteristics from a transparent state to a cloudy state by this heat, by which binary data or analog data are recorded. The data are reproduced by reproducing means 9, 10 which make photodetection.

摘要： PURPOSE:To accurately write and read out information and to lessen the wear of a magnetic head and card by providing revolving rollers which come into contact with the magnetic card at the time of writing and reading out on a mold which exposes the surface of the magnetic head and is fixed at the circumference. CONSTITUTION:The surface of the magnetic head 1 is exposed and the circumference thereof is molded by a resin 2. Ball bearings 3 made of iron exist on both sides and the highest part is the same height as the surface of the head 1. The rollers 5 exist above the head 1 at a specified spacing. The card is inserted between the rollers 5 and the head 1 and the writing/reading out of the information are executed. Since the ball bearings 3 exist on both sides of the head 1, the pressure by the camber, etc., of the card is dispersed to the ball bearings 3 and the pressure to the head 1 is decreased. The wear of the head 1 is, therefore, lessened and the life is prolonged.

摘要： PURPOSE:To record the measuring values of various sensors in accordance with the lapse of time and to miniaturize and lighten the title data logger card by storing a measuring value of a built-in miniaturized sensor or another sensor in a memory integrating circuit every output of a time signal from a timer circuit. CONSTITUTION:The data logger card is constituted of a microsensor 5 built in a normal IC card, a memory integrating circuit 6, a timer circuit 42 for outputting a time signal every previously set time, a miniaturized sensor 1A, and a connector 7 for connecting another sensor 1B. A gate circuit 41 is connected between the connector 7 and the processor 5 and a control circuit 43 opens the circuit 41 every output of a time signal from the circuit 42, and after the lapse of a fixed time, closes the circuit 41. Thereby, the an output signal from the sensor 1A or 1B is inputted to the processor 5 only in the opening period of the circuit 41 and the measuring value is stored in the circuit 6. Consequently, the measuring values of respective sensors can be recorded in accordance with the lapse of time and the data logger card can be miniaturized and lightened.

摘要： PURPOSE:To shorten an access time by preventing a defective loop data from being inputted to an RAM of a sequencer. CONSTITUTION:A shift register 50 outputs a write data WD1 by 1-bit each whenever a clock CLK is inputted. For instance, when a write data is 11011100-, and a defective loop data is 11101111-, the fourth clock CLK is stopped by a function of a NAND gate G1, therefore, a write serial WD2 becomes 110011100-, and it passes through a major loop 42 and is written all at once in each minor loop 31, 32-. A shift register 52 closes the NAND gate G1 when the fourth loop DL from an ROM26 is ''0''. As a result, if a read-out serial data RD1 is 110011100-, a read-out parallel data RD2 becomes 11011100- obtained by eliminating No.4 and putting close No.5 and thereafter to 1-bit before, and becomes equal to the write data.
摘要翻译：目的：通过防止有缺陷的环路数据被输入到定序器的RAM来缩短访问时间。构成：每当输入时钟CLK时，移位寄存器50将写入数据WD1输出1位。例如，当写入数据为11011100-并且有缺陷的环路数据为11101111-时，第四时钟CLK由NAND门G1的功能停止，因此写入串行WD2变为110011100-并且它通过主循环42并且在每个次循环31,32-中一次全部写入。当来自ROM26的第四环路DL为“0”时，移位寄存器52关闭NAND门G1。结果，如果读出的串行数据RD1为110011100-，则读出的并行数据RD2变为11011100，通过消除No.4并将其关闭到5号，之后为1位，并且变为等于写数据。

摘要： PURPOSE:To shorten an access time in case of setting an address, by writing in advance plural groups of marker codes in a minor loop which is used for a marker loop for detecting an address of the minor loop. CONSTITUTION:1 group of marker codes M1- written in a minor loop 3-1 for marker loop which is used for detecting a minor loop address is read out by a bubble detector 6 for a minor loop, and is set to a shift register 12. Subsequently, when said code coincides with a code of a register 8 for a marker code, which is set by a bubble address register of a controller 9, a flag 1 is set to the controller 9 by a comparator 13 and an FF7. As a result, a period by the controller 9 is started, an error of the text codes M1- set to the register 12 is checked through a buffer 15, address control is executed without passing through a major loop, and an access time in case of setting an address is shortened.
