摘要： An optical system of an optical recording apparatus forms a main spot and sub-spots preceding and succeeding the main spot on a signal recording medium. The optical system is set such that the sub-spot is shifted from the main spot in the direction orthogonal to a signal track by a distance expressed by an expression (2k−1)P/4(k=natural number), in which P denotes a distance between adjacent signal tracks on the signal recording medium. Thus, the sub-spot succeeding the main spot can be used to effectively read the state of a signal recorded on the signal recording medium by the main spot.

摘要： For an overwriting operation, recorded data is read from a disk, and a bit clock is reproduced from the read, recorded data in a clock reproduction circuit (7). Data processing in an encoder (14) is performed in synchronism with the reproduced bit clock. With the above, recording data is output from the encoder (14) in synchronism with the recorded data in the disk whereby recording data to write onto the disk for overwriting is synchronized with the recorded data. A defined recording region is thus precisely overwritten.

摘要： When a buffer underrun decision circuit decides that a buffer underrun is about to occur, data recording on the disk is interrupted by a recording control circuit. On the other hand, when the buffer underrun decision circuit determines that a buffer underrun situation has been avoided, data recording is resumed by the recording control circuit. At this time, data recording is resumed from a position of the disk which is continuous to data recorded by the time the data recording was interrupted, thereby recording new data continuous to the last recorded data.

摘要： When a record decision unit 22 judges that recording has been interrupted, the recording data in a predetermined frame is ended. Data are continuously recorded onto a disk until the frame synchronous signal duration following the predetermined frame. Thereafter, the control output generated from the head output controller 14 is controlled to interrupt the recording operation. When the record decision unit 22 judges the resuming of recording, the control output from the head output controller 14 is controlled to resume the recording operation onto the disk from the frame synchronous signal duration in which the recording of data onto the disk has been interrupted.

摘要： An error signal generating circuit for adjusting a position of a sub-beam on an optical disc to a correct one. A timing circuit generates a test signal so that a driver drives a tracking coil. As a result, a difference signal is generated in a difference signal generating circuit and is then compared to a reference value in a comparing circuit. A controlling signal is generated in a controlling circuit in reply to a comparing error so as to be held in a holding circuit. The thus held controlling signal is converted into an analog signal in a D/A converter and is then applied to a VCA to vary the amplifying rate, such that the difference signal becomes zero when a correct tracking operation is being carried out.

摘要： A speed control apparatus for a direct current motor comprises a bridge circuit having an armature in one side thereof, a direct current voltage source, and a series connection of a switching transistor and an inductor inserted between the direct current voltage source and the bridge circuit. A detecting transistor detects an unbalanced voltage of the bridge circuit and control transistors are responsive to the detection to control the switching transistor to be turned on or off. The inductor stores a magnetic energy when the switching transistor is turned on and supplies an electromotive force induced by the stored magnetic energy to the bridge circuit when the switching transistor is turned off. To that end, a diode or a transistor cooperates with the inductor and the bridge circuit to constitute a closed loop. A capacitor is connected in parallel with the armature, thereby to restrict the operation of the detecting transistor and thus the on/off-period of the switching transistor.

摘要： An optical disk recording and playback device comprises a first laser driving circuit that supplies a driving signal to a first laser diode, a second laser driving circuit that supplies a driving signal to a second laser diode, a signal recording pulse generating circuit that generates a signal recording pulse signal in accordance with a signal to be recorded on a signal recording layer, and outputs the signal recording pulse signal to the first laser driving circuit, and an image recording pulse generating circuit that generates an image recording pulse signal in accordance with a signal to form an image on an image recording layer, and outputs the image recording pulse signal to the second laser driving circuit. When recording of a signal to the signal recording layer and recording of an image to the image recording layer are simultaneously performed, the first laser diode and the second laser diode are controlled to prevent light emission from simultaneously occurring at recording levels.

摘要： At the time of data recording onto a disk, when an external power source connection detecting circuit (12) detects that connection of an external power source is released, the currently set rotation speed is recognized. When the current rotation speed cannot be achieved in a maximum speed restricting mode, the processing speed is switched to the maximum speed that can be achieved in the maximum speed restricting mode. At the time of data reproduction on a disk, when the external power source connection detecting circuit (12) detects that the connecting power source is switched to the external power source, the processing speed is automatically switched to the maximum disk rotation speed regardless of the maximum speed restricting mode.
