摘要： An information recording-reproduction method wherein: upon reproducing, recorded information corresponding to a predetermined number of sectors from the leading sector of each of a plurality of information tracks on an optical disk is preliminarily stored on a buffer memory, and during a period in which the optical pickup is shifted to another information track, the recording information, stored in the buffer memory, is reproduced; and upon recording, during a period in which the optical pickup is shifted to another information track, recording information is temporarily stored in the buffer memory, and after completion of the recording, the recording information is recorded on the optical disk. In this method, information tracks, which are formed on the optical disk discontinuously with one .another, are regarded as if they were continuous tracks, and the apparent recording and reproducing operation is carried out continuously.

摘要： First, a recording magnetic field is generated by a magnetic head using a coil drive current a.sub.1, and a first data signal is recorded on a groove of a recording layer of a magneto-optical disk. Thereafter, similarly, a second data signal is recorded on the same groove as above by a coil drive current a.sub.2. In this case, the first and second data signals have different signal frequencies which do not overlap each other. The amplitude A.sub.1 of the coil drive current a.sub.1, is set greater than the amplitude A.sub.2 of the coil drive current a.sub.2. This arrangement permits multiple recording and increases the recording capacity of the magneto-optical disk.

摘要： An information recording and reproduction apparatus uses a recording medium that contains information which prohibits digital copying. A reproduction section reproduces the desired informatiion stored on a first recording medium. A recording section records the reproduced output at a desired position on a second recording medium. However, an erasing section erases the information from the first recording medium during the process of recording that information on the second recording medium. The first and/or second recording medium cannot be removed from the information recording and reproduction apparatus until the erasing operation is completed.

摘要： Pieces of leading compressed information, each of which corresponds to a predetermined number of blocks of each of a plurality of programs recorded on an optical disk, are successively read therefrom, and stored in a buffer memory in a compressed state as they are. Upon reproducing a certain program, the corresponding leading compressed information is read from the buffer memory, and reproduced after having been subjected to a decompressing process in an information-decompression processing circuit. The program is continuously reproduced by reading compressed information corresponding to the predetermined number of blocks following the leading compressed information from the optical disk and supplying the compressed information to the buffer memory. With this arrangement, it is possible to eliminate a slow switching operation in the case when programs are switched to start reproducing a different program.

摘要： A data recording and reproducing apparatus uses a rewriteable optical disk with pre-recorded absolute address information, and comprises a data compression circuit for dividing and compressing continuous digital data into compressed plural data blocks, an expansion circuit to restore the compressed data to the original expanded form, and a buffer memory. Data is compressed in discrete data blocks and is recorded sequentially block by block to the optical disk. The compressed data is likewise read block by block from the disk during data reproduction. Using the data expansion circuit to expand the compressed data one block at a time, the data recording and reproducing apparatus can reproduce the original continuous digital data stream. Plural continuous digital data selections can thus be reproduced by alternately fetching data for the plural selections from the disk in compressed data block units and temporarily storing the data to a buffer memory for expansion.

摘要： An information recording and reproducing device has a first recording clock generation circuit which generates a clock based on pre-recorded information on a magneto-optical disk, a second recording clock generation circuit and a switching circuit The switching circuit selects a first recording clock when recording information is of discrete information and selects a second recording clock when recording information is of successive information. Moreover, in the present device, a first reading clock is used as well as a second clock as a clock for reading out the reproduced data from the magneto-optical disk, which had been once stored in memory. The second reading clock having a reference frequency is generated by a second clock generation circuit and is used for reading out successive information such as music information. The first reading clock in synchronization with the reproduced signal is generated by a first reading clock generation circuit and is used for reading out discrete information such as computer-use data. In addition, in the case of discrete information, it is possible to start recording/reproducing operation immediately after an optical head reaches a desired position, thereby permitting to shorten an access time.

摘要： A data recording/reproducing apparatus uses a single recording medium in which absolute address data are previously formed. Also, the data recording/reproducing apparatus has a first memory for recording and a second memory for reproducing. Audio data reproduced from the recording medium is stored in the second memory at a first transfer rate, and the audio data stored in the second memory is sequentially read at a second transfer rate lower than the first transfer rate to be audio-reproduced, while audio data inputted from external is sequentially stored in the first memory at the second rate and the audio data stored in the first memory is read at the first transfer rate to be recorded on the recording medium. The aforementioned reproducing and recording operations are alternately repeated. Thus, the data recording/reproducing apparatus allows audio data recording operation to be concurrently performed during audio reproduction with the single recording medium.
