A D player 1 and headphones 2 including a remote controller 2a and a pair of speakers 2b, 2b are detachably connected via an adapter 3.

First, a portable CD player 1 used as an audio reproducing device will be described. FIG. 2 is a block diagram showing the portable CD player 1.

That is, as shown in FIG.
Is rotated by the spindle motor 5 and information is read by the optical head 6. The optical head 6 irradiates the disk 4 with laser light, and reads, for example, information (audio signal) recorded in the pit form on the disk 4 from the reflected light.

In order to read data from the disk 4 in this manner, the optical head 6 includes a laser diode 6c as laser output means, a polarizing beam splitter,
An optical system 6d including a four-wavelength plate, an objective lens 6c serving as a laser output terminal, a detector 6b for detecting reflected light, and the like are mounted. Objective lens 6c
Is held by a biaxial mechanism 7 so as to be displaceable in a disk radial direction (tracking direction) and in a direction approaching / separating from the disk (focus direction).
The whole is made movable in the disk radial direction by a thread mechanism 8.

The information detected from the disk 4 by the optical head 6 by the reproducing operation is supplied to the RF amplifier 9. The signal amplified by the RF amplifier 9 is transmitted to an RF equalizer 1 in a digital signal processor (hereinafter referred to as DSP) 10.
1 is supplied. The RF equalizing unit 11 performs an arithmetic operation on the supplied information to execute a reproduction RF signal (EFM signal), a tracking error signal TE, and a focus error signal FE.
And so on.

The reproduced RF signal is supplied to an asymmetry correction circuit 1
2, a signal binarized via the RF-PLL circuit 13,
That is, as an EFM signal (8-14 modulated signal),
The signal is supplied to the demodulation unit 14. The RF-PLL circuit 13 generates a reproduction clock synchronized with the EFM signal by a so-called PLL operation, and supplies the reproduction clock to the EFM demodulation unit 14 as a clock for the decoding process. The EFM signal is subjected to EFM demodulation by the EFM demodulation unit 14, and
A sub-code component, which will be described later, is extracted, and the sub-code processing unit 15 decodes the sub-code data. For example, subcode Q data is extracted.

The subcode data is transmitted via a CPU interface unit (hereinafter referred to as a CPU-IF) 16.
This is supplied to the CPU 17 functioning as a system controller of the CD player.

The data subjected to the EFM demodulation by the EFM demodulation unit 14 is written into the ECC-RAM 18, and the error correction process as the CIRC decoding is executed through the read / write process in the ECC-RAM 18 by the error correction unit 19. . So-called C1 correction and C2 correction are performed.

The data subjected to the CIRC decoding is subjected to a deinterleave process by a deinterleave circuit 20, thereby performing 16-bit quantization,
The signal is demodulated to a so-called digital audio data format such as 4.1 KHz sampling. The digital audio data DT is temporarily stored in the buffer memory 22 under the control of the memory controller 21. And
Data (digital audio data DT) read from the buffer memory 22 at a predetermined timing is converted into an analog audio signal S _A by the D / A converter 23.
The signal is supplied from the terminal 24a of the headphone jack 24 to the headphone 2 via the external adapter 3, and is reproduced and output as, for example, L and R audio signals.

The buffer memory 22 is composed of a D-RAM, and has a capacity for storing, for example, digital audio DT for about 3 seconds as reproduced sound. Of course, a larger capacity may be used. Also, it is not always necessary to use a D-RAM.

Therefore, even if a track jump or the like occurs due to disturbance or the like, and data reading from the disk 4 by the optical head 6 is temporarily stopped, the buffer memory 22
, Can be continued, so that the reproduced sound is not interrupted. In this case, the optical head 6 may restart reading from an appropriate position while the reproduction by the stored data is continued.

By the way, due to the difference between the write bit rate and the read bit rate of the buffer memory 22, the amount of data stored in the buffer memory 22 may reach a full capacity at some point. In this embodiment, normally, the transfer rate is adjusted so that the accumulated amount of the buffer memory 22 does not reach the full capacity, so that the interruption of the writing (that is, the writing standby by one track jump) does not have to be executed. Things. The track jump is required only when the continuity of the read data is interrupted by the frame check or when an error correction impossible state occurs, and the number of track jumps executed during reproduction is reduced as much as possible. .
