Abstract: PURPOSE:To make it possible to quickly access a disk and to perform a high speed reproduction and also to enhance error correctability. CONSTITUTION:Data is recorded by adding dual parity of internal parity and external parity to an optical disk 1. The internal parity is added to interleaved data, and is used for correcting an internal code, while the external parity is added to noninterleaved data and the internal parity, and is used for correcting an external code. Reproducing data from the optical disk 1 is supplied to a ring buffer memory 5 to be stored, and is also supplied to an error correction circuit 71, where the external code is corrected. A corrected result is supplied to the ring buffer memory 5, and is superscribed. The data stored in the ring buffer memory 5 is read out again to the error correction circuit 71, where the internal code is corrected. The data corrected on the external code is used for detecting a sector address in a sector detecting circuit 72, and at the time of special reproducing, the external code is only corrected.

Abstract: PURPOSE:To shorten the period of time required for starting a reproduction by setting the rotational speed of a disk at the time of reading TOC data faster than that at the time of reading program information. CONSTITUTION:When a disk 1 is set on a play position, an optical head 3 is moved to the read-in area of the disk 1 and the focusing of the head 3 is executed. Then, a spindle motor 2 is started, and accelerated to a set number N1 of revolution, and at the time of the number N1, the TOC data is read. After the read data is decoded by a decoder 7 via a reading signal processing section 4, it is stored in a RAM 11 via a system control section 10. After a reading is completed, the speed of a motor 2 is reduced down toward the prescribed number N2 of revolution at the innermost periphery of a program area, and at the time of the number N2, a series of processings of a TOC reading mode is finished. After that, unless a music to be performed is specified, a first music is performed.

Abstract: PURPOSE:To prevent the locking-off of a PLL circuit and to improve reproducing ability by calculating the mean value of the length of respective patterns and determining the waveform length of the respective pattern in an EFM signal regenerated from a compact disk. CONSTITUTION:The regenerative signal EFM read out of the compact disk is given to a phase measurement circuit 1 and a frequency measurement circuit 2. The circuit 1 is identical to a conventional digital PLL cirucit and the circuit 2 is coinstructed as follows. That is, as to small pattern such as 3T and 4T (T; channel clock period) recognized as a frequency deviation having a large changing amount in wareform length due to polarity caused by high frequency, the waveform length is determined by calculating the mean value of the pattern by averaging circuits 5 and 6. The frequency deviation is obtained by weighting as prescribed the output signals of the circuits 5 and 6 with a weighting circuit 7.

Abstract: PURPOSE:To prevent a disk unreproduced due to the unreading of TOC by recording a signal in which a weak frequency is digitized instead of zero of main information data. CONSTITUTION:A data frame consisting of preamble, sub code TOC, and a high frequency weak signal is recorded on a TOC block of read-in provided at the inner peripheral part of a digital audio disk. In other words, the high frequency weak signal is analog-digital converted and digital-modulated and recorded on a music signal area instead of data '0'. The level of the high frequency weak signal set at the one so that an LSB after digital conversion can be changed between 0 and 1.

Abstract: PURPOSE:To improve an error rate of even a disk with poor symmetry by setting a dead band to a pattern whose period is measured short in a digital PLL generating a clock based on a reproduced EFM signal of a compact disk. CONSTITUTION:A DELTAT measuring counter 11 counts system clocks SCK between change points of a reproduced EFM signal SEFM. Then the frequency of a digital controlled oscillator 3 is controlled so that an output of the DELTAT measuring counter 11 is zero. In the case of a 3T pattern, a dead band is provided for time axis fluctuation by + or -3 clocks. Moreover, a frequency correction data with respect to the time axis fluctuation by + or -2 clocks is selected small in the 3T pattern. Thus, when a large frequency fluctuation is caused in the 3T pattern in the case of a disk with poor symmetry, the fluctuation of the oscillating frequency of the digital control oscillator 3 is avoided, the oscillator 3 is operated stable and the error rate is improved.

Abstract: PURPOSE:To output a phase control data from the phase control circuit controlled in an excellent way even with an input signal with different phase error from a leading edge and a trailing edge by providing an edge detection means, a delay means and a phase error detection means to the phase control circuit. CONSTITUTION:An input signal Sin is supplied to a leading edge detection circuit 16 as a signal Se via an input terminal 1, latch circuits 11, 13 and an EXOR circuit 15. The circuit 16 detects a leading edge of the signal Se and an edge detedction signal Sf is supplied to a counter 17 and an EN register 18. Then a delay circuit 19 receivers an output data MSB from the register 18 and an OR data PLS from an OR circuit 21 to retard them till the data PLS rises to logical 1 next, and they are supplied to a clock generating circuit 30 as phase control data respectively. A phase error of a comparison signal PLCK to the signal Sin in such a case is expressed by a data MSB representing the presence of the error. Then the phase control data able to be controlled in an excellent way is outputted even from and input signal whose phase error differs from the leading edge and the trailing edge.
