Abstract: The disk recording appts. sequentially inputs data to a memory (14) at one transfer rate. This data is subsequently read out at a second, higher transfer rate and recorded to disk (2). The amounts of data read from the memory are set so that there is a writing space in memory. During playback, the recorded data are reproduced at a rate, higher than the rate for outputting the data, and stored in a memory (22). Again the amount of data read always maintains a minimum amount of data in the memory (22).

Abstract: The appts. records on an optical disc (2) having a memory (14) for storing input digital data compressed from a continuous signal. A signal encoder (15) arranges data from memory (14). The arrangement is multiple clusters at an interval of a set number of sectors annexing to each a linking sector. The cluster data is interleaved for the recording circuit (3, 4). An abnormality detection circuit (30) acts through a controller (7) to inhibit recording upon detection of abnormality. This performs a read out control of the memory.

Abstract: During recording inputted data are sequentially written into a memory (14) at one transfer rate and are read out at a second, higher transfer rate for recording on a record medium (2). The reading of the memory (14) is such that data in a preset first amount are successively read from the memory (14) to always ensure a write space in the memory (14) which has a capacity which is higher than a predetermined second amount when the amount of the inputted data stored in the memory (14) exceeds the first amount. During playback, the recorded data are reproduced at a second transfer rate, which is higher than a first transfer rate required for outputting the reproduced data, and are written in a memory (22). The thus written data are successively read out of the memory (22) as reproduced output data at the first transfer rate. The writing of the reproduced data to the memory (22) is controlled so that a second amount of the reproduced data is written into the memory (22) and an amount of reproduced data, not less than a first amount, is always stored in the memory (22) when the amount of the reproduced data stored in the memory (22) becomes not higher than the first given amount.

Abstract: Un aparato reproductor de discos para reproducir datos grabados en pistas en un soporte (2) de grabación en disco, comprendiendo el aparato: medios de reproducción (3, 4) para reproducir datos grabados a una segunda velocidad de transferencia; medios (22) de memoria en los que los datos reproducidos leídos por los medios de reproducción (3, 4) son escritos a la segunda velocidad de transferencia, y desde los que los datos escritos así son leídos como datos de salida reproducidos a una primera velocidad de transferencia que es menor que la segunda velocidad de transferencia; y medios (7) de control para causar que los medios de reproducción (3, 4) controlen la posición de reproducción en el soporte (2) de grabación en disco de modo que los datos reproducidos escritos en los medios (22) de memoria de una manera interrumpida son leídos sucesivamente de las pistas de grabación en el soporte (2) de grabación en disco, en el que los medios (7) de control paran la escritura de los datos reproducidos en los medios (22) de memoria cuando los medios de reproducción (3, 4) resultan incapaces de reproducir los datos grabados debido a una perturbación física indeseada del soporte (2) de grabación en disco y después reanudan la escritura de los datos reproducidos en los medios (22) de memoria cuando los medios de reproducción (3, 4) son capaces nuevamente de reproducir los datos grabados.

Abstract: An optical recording medium is provided which has a substrate and a signal recording layer provided on the substrate and in which an information signal is recorded in the form of microscopic pits. A light beam is focused on the signal recording layer and some change of the light beam carried by a return light from the signal recording layer is detected to read the information signal recorded on the signal recording layer. The optical recording medium has a diameter of 65 mm or less and a thickness of 0.4 to 0.7 mm. An information signal recording area extends outwardly from a radial position of 12.5 mm or less from the center of the medium. The ratio in area between the information signal recording area and non-signal recording area is 3.4 or more. The storage capacity of this medium is 2 gigabytes or more. The optical recording medium has formed at the center thereof a center hole around which an annular table-abutment convexing to one side of the medium is formed. A magnetic-clamping hub is installed in the center hole and thus the medium is magnetically clamped to a rotation driving mechanism of an optical recording and/or reproducing apparatus. The compactness and high density of recording of the optical recording medium will contribute greatly to a further compact structure of a recording and/or reproducing apparatus in which the medium is to be used.
