Abstract: Because a series of data is recorded continuously, the recording quality of data recorded in course of recording cannot be evaluated. Accordingly, the laser output cannot be controlled properly and there are a deterioration and dispersion of the recording quality. Further, when the recording lasts for a long time, the temperature in the vicinity of laser rises due to the heat from the inside of a disc drive and the recording quality is deteriorated. To solve this, a series of data to be recorded is split and recording is made intermittently in a split data unit. The recording quality is evaluated by reproducing the data recorded nearby before each split data is recorded using a duration and control is performed by reflecting the evaluation result in the laser output so that the recording quality can be maintained satisfactorily over a series of the whole data to be recorded.

Abstract: An operation for recording a recording signal onto a disk (1) is interrupted, when an amount of signal data stored in a buffer RAM (11) for temporarily storing the recording signal is less than an interruption setting value during performing of the recording operation. Moreover, when the amount of signal data stored in the buffer RAM (11) increases and indicates a resumption setting value, the signal recorded on the disk (1) before interruption is reproduced, and the recording operation is resumed based on the reproduced signal. Moreover, recording properties are detected by the signal reproduced before resumption of recording.

Abstract: An optical recording method and apparatus with different recording rates are provided for effectively increasing the average recording rate. The optical recording method includes the steps of: controlling a recording rate with a constant linear velocity (CLV) control mode; recording data; judging whether the recording rate has to be increased according to a rotating speed of a spindle motor or a recording position; and performing a process for changing the rotating speed if the recording rate is increased, and continuing recording data at the same recording rate if the recording rate is not increased. The step for changing the rotating speed includes the steps of: pausing recording data; registering a paused zone of a disc; determining a new rotating speed of the spindle motor, and driving the spindle motor at the new rotating speed; and linking recording zones to continue recording data at a new recording rate from the paused zone, when the rotating speed of the spindle motor is stable.

Abstract: The present invention relates to method and apparatus of recording an audio signal composed of several tracks on a recording medium in a manner that the tracks can be distinguished each other in a recorded audio signal. The present track-synchronous recording method detects a no-sound interval longer than a predetermined time that is included in an input audio signal during recording the input audio signal, and records an audio signal following the detected no-sound interval with a different track number from that of recorded audio signal preceding the detected no-sound interval. Therefore, it is possible to individually distinguish tracks on a copy medium even though those not having any track information are copied thereto from an original at a time.

Abstract: When an error has occurred during the recording of an optical disk, the track recording system is changed from a variable-length packet write system to a fixed-length packet write system employing an arbitrary length (step S2). A check is performed to determine whether before the error occurred the number of blocks used for recording was equal to or greater than 300, which is the minimum block length for one track (step S4). When at least 300 blocks have not been used for recording, by using as a recording unit a fixed-length packet having the arbitrary length, the dummy data are continuously recorded until the used block count reaches 300 (steps S5 to S7). Thus, when an error occurs during the recording of dummy data (Yes at step S6), one fixed-length packet is added (step S8) and the recording of dummy data is continued.

Abstract: An audio disk/memory disk player. At the time of playing a disk, TOC information in a lead-in area will be read out first after loading of the disk is complete. The player determines whether the disk to be played is an audio disk (CD) or a memory disk (CD-ROM) based on identifying information in the TOC information. If the disk is the memory disk, the operation goes directly to a pause mode so that upon reception of a read command transition to the searching for a designated address is promptly executed to quickly read out the desired data. Only when the disk being played is the audio disk, the audio system is changed to the audio disk from another source, thus permitting a user to view a map while listening to the previous source. When playing for an area having a series of group information recorded is complete in special play mode, the mode is quickly changed to the pause mode in the case of the memory disk to wait for the read command, thus ensuring quick reading of designated map data.
