Abstract: An optical recording method for recording data on an optical disc by using a laser beam. When an optical disc is inserted into an optical recording device (step S1), a power calibration area (PCA) is searched so as to be used for optimum power calibration (OPC) on the optical disc. At the position found, an optical pickup is made to wait (step S4). After this, when a data recording operation input is received (step S6), the OPC operation is executed at the wait position (step S7) and optimum power is obtained. After this, the optical pickup is moved to the data recording area of the optical disc (step S10) and data is recorded in the data recording area of the optical disc by the optical pickup (step S11).

Abstract: A memory controller (12) is equipped with a memory data search circuit (35) for carrying out an identifying operation of management information corresponding to a segment located in front of or behind a segment serving as a reference for an editing operation on a recording medium (1) through search and comparison processing of managing information (U-TOC). A system controller (11) does not receive search data and execute the data search but only sets the comparison standard and an initial value and outputs an execution control signal. The editing operation performed reduces wasted space on the recording medium (1), such as a disc, and eliminates "trash areas" which are not addressable in the U-TOC.

Abstract: In a memory control device (12) for controlling write-in/read-out operation for memory means (13), a sector data storing area and an additive area are set in each of sector-based data storing areas in the memory means. A prescribed datum is stored in the additive area associated with the sector-based data stored in the sector data storing area. The access addresses for the additive area are generated on the basis of the sector count value when the sector data write-in or read-out is carried out in the memory means (13). The access addresses are calculated by the memory control device (12).

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: In reproducing a recording medium (90) having a main data area for recording main data, an auxiliary data area for recording auxiliary data such as image data and text data corresponding to the main data, a first control area for controlling the main data area, and a second control area for controlling the auxiliary data, the auxiliary data is reproduced in a predetermined timed relation with the main data based on synchronization information recorded in the second control area.

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.

Abstract: A reproduction apparatus (1) and method and a recording apparatus and method by which two different kinds of data can be reproduced and recorded efficiently are disclosed. When main data are intermittently read in from a recording medium (90), periods within which reading in of the main data is not performed appear inevitably, and the periods are made use of to read in sub data from the recording medium (90), thereby allowing synchronized reproduction of the main data and the sub data which relate to the main data. On the other hand, when main data are intermittently written onto a recording medium (90), periods within which writing of the main data is not performed appear inevitably, and the periods are made use of to write sub data onto the recording medium (90), thereby allowing parallel recording of the main data and the sub data.

Abstract: A digital audio signal reproducing apparatus for reproducing digital audio data at a constant data rate by reading digital audio signals recorded on a recording medium (2) after bit compression, in which the compressed data are read out from the recording medium and written in a memory (22) when the amount of the non-read-out data in the memory (22) becomes lower than a predetermined amount, and data read-out from the memory (22) is discontinued when it becomes impossible to write data in the memory (22), thereby to establish a stand-by state by way of performing memory control. On actuation of a pause key (8), data read-out from the memory (22) is discontinued. On releasing the pause key (8), the read-out operation from the memory (22) is re-initiated.
