Abstract: PROBLEM TO BE SOLVED: To improve operability at the reproduction of contents recorded by air check. SOLUTION: A reception timing for text information in a specific form corresponding to music name information among various kinds of text information is identified. The music name information is transmitted at the start of broadcasting of the music, and therefore the reception timing corresponds to a timing at which the music is started in the broadcasting. In recording the broadcast sound, therefore, points (addresses on the disk) corresponding to the timings are made program separation points TM1-TM4, whereby the track on which broadcast sound is recorded is divided to tracks (TK1-TK5) by the start points of the music, thus enabling an access to the start of the music at the reproduction time.

Abstract: PURPOSE:To eliminates interruption of sound by making the reproduction be in stand-by state for a prescribed time, when track jump of the prescribed numbers and reproducing operation of sound data of the prescribed length are repeated and cue reproduction or review reproduction are performed and if reproducing scanning after track jump is started in a silent data area. CONSTITUTION:Writing data read out from a magneto-optical disk 1 in a buffer RAM 13 is performed with continuous 1.41 M bits/sec, operation in which data from the RAM 13 is read out and data is supplied to an encoder/decoder section 14 is performed with 0.3 M bits/sec. Thereby, even when storage capacity of the RAM 13 is 1 M bit, data of full capacity can be stored in the RAM 13 for 0.9 seconds from start of reproducing, data can be outputted for three seconds without supplying data from the disk 1, reproducing output is continued until reading out data is started again even if a tracking servo and a focus servo are in off-state, and interruption of sound is prevented.

Abstract: PURPOSE:To simplify circuit configuration and to minimize the number of times of change of processing by selecting one of plural compression modes for bit compression processing, storing transiently recording data to which the compression processing is applied, and recording successively the recording data from a storage means on a disk shape recording medium. CONSTITUTION:A means 7 which selects one of the plural compression modes for the bit compression processing, the storage means 14 which stores the recording data to which the compression processing is applied transiently, and a recording means 16 which records the recording data from the storage means 14 successively on the disk shape recording medium 2 are provided. When the compression mode is switched selectively by the compression mode selection means 7 in recording, buffering between input data and actual recording data is performed by the storage means 14. Thereby, it is possible to simplify the circuit configuration and to minimize the number of times of change of the processing.

Abstract: PROBLEM TO BE SOLVED: To continue recording or reproducing data while securing continuity in the data even when abnormalities happen in recording or reproducing operations such as track jumps.
SOLUTION: If an abnormality detector 30 detects a track jump when recording data on an optical disc 2, data read to the memory 14 is stopped until the operation returns normal based on the detected track jump. When the read is resumed to memory 14, data are recorded on an optical disc 2 seamlessly over the stop time caused by the track jump based on the recording position control of the optical disc 2 by a system controller 7. When reproducing, the data are reproduced from the optical disc 2 continuously regardless of the points of record stop and start.

Abstract: PROBLEM TO BE SOLVED: To exactly identify and process L and R channels by adding identifiers to identify either even sectors or odd sectors to the sectors to be stored and storing these sectors in accordance with the results of discrimination as to whether the stored sectors are the even sectors or the odd sectors. SOLUTION: A memory controller 12 outputs a channel identification signal in order to enable an encoder/decoder section 14 to identify that a sound frame of the two sectors is L channel data at a ratio of once per two sector. For example, the controller emits the channel identification signal at the output timing of the top sound frame of the even sector and has this signal recognized with the L channel by the encoder/decoder section 14. At this time, this identification signal is not outputted in the odd sector. Then, the sound frame is known to be the sound frame of the L channel data captured at the time the identification signal is supplied in the decoder section 14 and thereafter, the processing is successively executed as the R, L and R channels by every sound frame to be captured thereafter and, therefore, the erroneous processing of L as R does not occur.

Abstract: PROBLEM TO BE SOLVED: To provide an editing mode for updating management information so that a desired track can be inserted into a position which is specified by a user. SOLUTION: When 'Insert' mode is selected at the time of record mode, a system controller requests insert point specification (S001-S003). A user searches a position which is requested, for example, by reproduction operation, stores the address of the insert point when the search is completed, and performs recording operation at this point (S004-S007). When recording operation is performed, a free area is accessed and recording operation is initiated. The recording operation continues until a stop key is inputted from this point (S008-S010). Then, after the recording stops (S011), a U-TOC area read into a specific area on a buffer memory is updated (S012).

Abstract: PURPOSE:To set a recording mode and a reproducing mode separately before and after a buffer RAM and to cope with an emergency recording, in a recording and reproducing device provided with a buffer RAM. CONSTITUTION:A means 8, 30 for dealing with and processing recording medium enable a reproducing mode operation in which read-out data read out from a recording medium is written in a memory and a recording mode operation in which write-in data written in a recording medium is read out from a memory, to be excuted. Also, input/output processing means 14, 32 being a signal system from a memory to an input/output section of a sound signal enable to perform recording mode operation in which input data inputted to record in a recording medium is written in a memory and reproducing mode operation in which output data read out and outputted from a recording medium is read out from a memory. And, a memory control means 12 enables, write-in or read-out operation in which one of the recording medium-coping and processing means and the input/output processing means is reproduced from a memory as the reproducing mode and the other is recorded in a memory as the recording mode, to be excuted.

Abstract: PURPOSE:To effectively utilize the recording area of an optical disk. CONSTITUTION:When some in sound data recorded on an optical disk 1 is erased in an editing mode, sound data recorded on an area next to an erased area is read in sequence by every one cluster based on TOC data temporarily stored in a TOC memory 27 by system controller 5 and temporarily stored in a RAM 22. A recording/reproducing system 2 is controlled so as to read this sound data and to record it again following the sound data recorded before the above-mentioned erased sound data. Also, when this re-recording is over, new TOC data is formed in the TOC memory based on the re-recorded sound data and the recording/reproducing system 2 is controlled so as to record this TOC data on the optical disk 1.
