    摘要： A magneto-optical disk recording and reproducing device, which carries out recording and reproducing for a magnetic super-resolution magneto-optical disk including a recording layer and reproducing layer, has a recording data processing circuit which records long recording marks at different positions between adjacent tracks in a radius direction, each of the long recording marks being larger in diameter than an aperture formed on the reproducing layer by projecting thereon the light beam. According to this arrangement, it is possible to continuously reproduce a data recording area with high accuracy and optimum reproducing power without being affected by adjacent tracks.

    摘要： An optical card recording and reproducing device including an optical head for emitting a light beam spot to the optical card having a plurality of parallel data tracks to which data is recorded; a transfer system for transferring the optical card and/or the optical head; and a track number confirmation means for confirming the track number recorded in the address data area in the data track of the optical card. The optical card recording and reproducing device also includes a transfer stopping means for stopping the optical head when an incorrect track number is deleted. The system minimizes the relative transfer distance between the optical card and the optical head, and at the same time, the total relative transfer distance of the optical card and/or the optical head when confirming the track number more than twice. Thus, the total time required for track number confirmation can be greatly shortened.

    摘要： An audio visual system includes an audio cassette tape player, a central processor unit, a TV screen for displaying a desired pattern in accordance with a data derived from the audio cassette tape player, and a speaker system for providing audio announcement in accordance with information derived from the audio cassette tape player. The audio visual system displays a problem and five typical answers thereto. The student introduces his answer through a keyboard unit. When, for example, an answer key 3 is actuated, the audio visual system drives the audio cassette tape player to locate a commentary suited for response to the actuation of the answer key 3 whereby the commentary associated with answer key 3 is displayed and announced.

    摘要： Recording mark forming method utilizing a device including a laser and a laser drive carried by a pickup having a movement drive wherein a control controls the drives to irradiate a recording medium with laser pulse sequences to form recording marks having recording mark lengths between a predetermined and maximum lengths, a top section, a last section including a cooling period, and an intermediate period. Heat of mark front edges is controlled by top section recording parameters classified according to recording mark lengths and recording parameters of first through maximum recording mark lengths are classified into a same group. Heat of mark rear edges is controlled by cooling start positions for cooling periods classified according to recording mark lengths. Cooling start positions for a second predetermined mark length through the maximum mark length are classified into a same group. The second mark length is longer than the first mark length.
