摘要： The present invention relates to a method for recording data on an optical data recording card. The present invention discloses practical data formats for solving the following problems: (1) the control of the operation for reading out unit readout arrays by means of a line sensor; (2) the establishment of synchronism with data pits in case of the readout operation, (3) the discrimination between the adjacent unit readout arrays; (4) countermeasure taken when readout errors occurs; and (5) efficient access to data.In order to solve the above-described problems, data pits are arranged in unit readout arrays; bars are defined for guiding the line sensor; and a format for indicating the center position of each unit readout array is prepared. Furthermore, special bars are also defined in order to correct the inclination of the line sensor. The data pits are arranged at a predetermined period and sync pits are provided to establish the synchronization with the pit period in case of the readout operation. In addition, discriminating pits are provided in order to distinguish between the adjacent readout arrays in case of the readout operation. The discriminating pits may be pits for discriminating the even-numbered unit readout arrays from the odd-numbered unit readout arrays or may be three pits so as to increase a degree of accuracy with which each unit readout array is discriminated.A format in accordance with the present invention is provided with special error check pits in order to take countermeasure when readout errors occur. Furthermore, in order to take countermeasure when readout errors occur due to local contamination on the optical data recording card, the data are distributed and then recorded. In order to perform the efficient access to data, required data representing a predetermined address value and so on are also recorded together with the general data. The present invention also discloses a method for forming pits by modulating the digital signal and an optical system as well as a signal processing system of a reading device used in connection with the optical data recording cards.The optical data recording cards on which are recorded the data by the method of the present invention are expected to be widely used in various fields as recording media for storage of computer programs, images, musical data and various data base.

摘要： Data can be recorded onto an optical card (102; 200; 601; 800) on which a plurality of tracks are parallelly arranged and can be reproduced therefrom. The optical card is supported by card supporting means (101; 501). This card supporting means is reciprocated in a first direction by card drive means (109; 511). An optical head (103; 503; 603) is provided above the optical card to selectively provide access to tracks by a light beam. This optical head is reciprocated in a second direction perpendicular to the first direction by head drive means (108; 507). The reciprocating motion of the card supporting means is accelerated and decelerated when the optical head scans on guide sections (G) provided on both the sides of the optical card. Error correcting codes are added to data recorded onto the optical card. Thus, error correction is made by an error correction circuit (136). Motors of respective drive means are enclosed with vibration proof metal (321, 323) and vibration proof rubber (322). The card supporting means (101) comprises pressing means (423) for pressing the upper surface of the optical card and positioning means (425) which can be in contact with the side surface of the optical card and away therefrom, thus to carry out positioning of the optical card. The card supporting means (501) is provided with contact surface (501a). By roller means (506) having rotation shaft (505) slightly inclined with respect to perpendicular (505') set up on the plane including the contact surface, optical card inserted from the outside is introduced toward the contact surface. The optical head (103) is ordinarily controlled by feedback control.
