Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a first device for reproducing an information recording medium once an information signal is digitally recorded, and at least an information signal reproduced by the first device. a second information storage medium for recording information on a second information recording medium;
The present invention relates to an example of an information recording device including the following device.

(B) Prior Art In recent years, a first information recording medium (for example, a first information recording medium) on which an information signal (for example, a music information signal) is digitally recorded.

Devices (for example, compact disc players) that play compact discs are commercially available, and a magneto-optical disc player that can record and play back information signals in the same signal format as compact discs has been proposed. (See "Radio Science, February 1985 issue," pages 99 to 103).

By recording the music information signal reproduced by the compact disc player with a magneto-optical disc player, it is possible to create a desired and original disc in the same way as with existing cassette tapes.

By the way, compact discs record subcode signals in addition to music information signals, b, ? : By using the signals of , it is possible to search for a wide variety of information.

Therefore, even when the music information signal reproduced by the compact disc player is recorded by the magneto-optical disc player as described above, it is desirable to record the subcode signal as well.

(C) Problems to be Solved by the Invention The present invention provides information that can be recorded together with subcode No. 15 when an information signal reproduced by a compact disc player is recorded by an optical i-disc player. The purpose is to provide a recording device.

B) Means for Solving the Problems In view of the above points, the present invention provides a first device for reproducing a first information recording medium on which an information signal is digitally recorded; and a second device for recording an information signal on a second information recording medium, the information recording device comprising: a second device for recording an information signal on a second information recording medium, and a search information signal included in the information signal reproduced by the first device is transmitted to the IX2 device. A conversion means for converting into a desired search information signal is provided, and the search information signal converted by the conversion means is recorded on the second information recording medium together with the information signal.

(E) Function According to the present invention, when recording the information signal reproduced from the first information recording medium onto the second information recording medium, the search information signal included in the reproduced information signal is transferred to the second information recording medium. The search information signal is converted in accordance with the recording position of the information signal recorded on the medium, and the converted search information signal is recorded on the second information recording medium together with the above-mentioned information signal.

(v) Embodiment The figure shows an embodiment of the present invention. In the figure,
(1) is a compact disc player, (2) is a music information signal output terminal, (3) is a subcode signal output terminal, (
4) is a magneto-optical disk, (5) is a Sun 1 pull-hold circuit, +6 Hiro A/D converter, (7) is a digital signal processing circuit, (8) is a subcode signal decoder, (9) is a microcomputer, C1α is memory,
C11l is a subcode signal generation circuit.

Next, the operation will be explained.

Among the information signals reproduced by the compact disc player (1), the music information signal (analog signal) from the music information signal output terminal (2) is sent to the sample hold circuit (5).
The signal is supplied to the A/D converter (6), converted into a digital signal, and then supplied to the digital signal processing circuit (7), where it is converted into an EFM (Eight to FourteenM
digital processing such as oduration) and interleaving are performed.

On the other hand, the subcode signal from the subcode signal output terminal (3) is demodulated by the subcode signal decoder (8),
It is supplied to the microcomputer (9). In the microcomputer ((1), the final position information (
For example, in the case of a music information signal, all calculations are performed with the subcode signal from the subcode signal encoder (8) (track number, performance time, etc.) and the position information (track number, performance time, etc.) of the music information signal that is currently being recorded. performance time, etc.). The subcode signal generation circuit (111 is a microcomputer (
A subcode signal is generated based on the calculation result of step 9), and the subcode signal is sent to the digital signal processing circuit (7) based on the timing signal (S) from the digital signal processing circuit (7).
).

The digital signal processing circuit (7) converts the signal into a desired signal based on the subcode signal and the music information signal, and supplies the signal to the writing/reading unit H, where the writing/reading unit α2 writes the signal to the magneto-optical disc. It is poured into.

Incidentally, in the above embodiment, a case has been described in which the music information signal and the subcode signal are separated and output from the compact disc player (1), but digital signal processing such as EFMFM demodulation video interleap error correction is performed. Needless to say, the present invention can also be applied to cases where digital signals are output.

In that case, since the digital signal is biphase modulated, it is necessary to demodulate it and separate the subcode signals.

Also, if you want to store the final position of information already recorded on a magneto-optical disc in the memory mark, you can manually input the position information, but you can enter the position information manually in the same place as the lead-in area of the compact disc. TOC(
The position information on the magneto-optical disk is stored in the same format as the Table of Content), and the contents are read out and stored in the memory GO! The information may be stored in the memory.

(G) Effects of the Invention According to the present invention, there is provided a first apparatus for reproducing a first information recording medium on which an information signal is digitally recorded.

An information recording device comprising at least a second device for recording an information signal reproduced by the first device onto a second information recording medium, the second device recording the information signal reproduced by the first device. Conversion means for converting a search information signal included in the reproduced information signal into a desired search information signal is provided, and the search information signal converted by the conversion means is recorded on the second information recording medium together with the information signal. This makes it possible to easily create a search information signal for the information signal recorded on the second information recording medium.
