JPS61150175A - Compact disk - Google Patents

Abstract

PURPOSE:To prevent the reproduction of an unnecessary sound through an erroneous operation by recording no sound on a track. CONSTITUTION:On a track 1 of a compact disk, no sound signal for a short time is recorded and on respective tracks after a track 2, sound signals A, B... are recorded. Accordingly, when erroneously designating a reproduction without designating the track, the sound is not reproduced since the track 1 has no sound, but when a play of the track 1 is completed, a standby condition by returning to the first step of the track 1 is obtained. As a result, an unnecessary sound is prevented reproduced due to an erroneous operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a compact disc in which acoustic signals are recorded on a disc by applying light wave technology.

2. Description of the Related Art In recent years, compact discs have become popular as a new medium for recording and reproducing music, replacing the so-called records that have been used in the past. In addition to the music signal, this compact disc contains a track number indicating the song number,
Furthermore, address information in minutes and seconds is recorded, which indicates the detailed performance position. Insert next page Taking advantage of this, many compact disc players are configured to automatically play music by specifying a track number or the like.

Problems to be Solved by the Invention When using such a compact disc and a player, it is possible to specify the correct song number, that is, the track number, to play, but due to a mistake in operation, the track number may not be specified. When playing a disc, generally the first track of the disc, track 1, is played, so an unexpected sound may be played, which may cause some inconvenience.

Means for Solving the Problems In view of the above-mentioned problems, the present invention provides a compact disc that can prevent unnecessary sound from being reproduced even if such an erroneous operation occurs.

In order to solve the above problems, the compact disc of the present invention records and reproduces audio signals by track number 2.
This is a structure in which a short period of silence signal is recorded as track 1 for subsequent recording.

Function When using the co/5 disc of the present invention, even if you play track 1 without specifying the track number due to a mistake in operation, the content will be silent, so you will not be able to use your hands or feet. The inconvenience of the sound being played does not occur.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

Figure 1 shows the track structure of a conventional compact disc, with track 1 having audio tracks, track 2 having audio tracks, and so on.
... is recorded. Speech mu is generally a sound mulberry, and of course it is not silent.

FIG. 2 shows the track structure of the compact disc of the present invention, in which audio signals are placed after track 2, and silence is recorded in track 1. track 1
The duration is around 3 seconds.

Figures 1 and 3 show state diagrams when the compact disc of the present invention is applied to a normal compact disc player. When the player is turned on or a new compact disc is inserted, the player is ready to play from the beginning of track 1. If you specify the track number in the correct procedure and issue a play command, the specified track will be played. For example, to play audio B on the disc shown in FIG. 2, track 3 may be designated. When the performance is finished, it returns to the beginning of track 1 and waits again. At this time, if you intended to play audio B, but accidentally gave a play command without specifying a track, the player would play track 1, but this track would be silent. Therefore, no sound is played from the player. Then, since the performance of track 1 ends in about 3 seconds, the player returns to the beginning of track 1 and waits. The operator realized that he had made a mistake because no audio was played, and then
Tracks can be specified correctly.

As described above, by using a compact disc in which around 3 seconds of silence is recorded on track 1, according to this embodiment, it is possible to prevent unplanned and unnecessary playback of audio due to erroneous operation, and the operator can can notify users of incorrect operations. In addition, by providing a silent section of around 3 seconds,
There is almost no negative effect on the audio capacity of a single compact disc.

In the present invention, the silent recording time of track 1 was set to about 3 seconds in the above embodiment, but it can be made shorter or longer if necessary.

For example, if the time is set to 1 second or less, the time to return to standby can be accelerated. Also, depending on the player, after track 1 has finished playing, tracks 2, 3, etc. continue to play.
In order to prevent the playback of unnecessary sounds and to notify the operator of erroneous operation, track 1 may be played for a certain length of time, for example 3.
Sometimes it is better to record silence for around 0 seconds to 1 minute.

Effects of the Invention As described above, by recording silence on track 1 of the FJA/d compact disc of the present invention, it is possible to prevent unnecessary sound from being played back due to erroneous operation.
