2. Description of the Related Art Regarding optical discs widely used as information recording media, those which are practically used at present are those which record video signals and audio signals and those which record digital audio signals. , Are classified into several types in terms of recorded information, such as digital data recorded by a computer. Of these optical discs, the one on which a video signal and an audio signal are recorded as information is usually called an optical video disc. For example, an image and audio of a movie originally produced to be shown in a movie theater. It is assumed that movie information, which is a recording signal based on a video signal and an audio signal, respectively, is recorded.

An optical video disc has an information recording surface on only one side or both sides to have a preset predetermined recording information capacity. The recording information capacity is, for example, an optical recording capacity. When reproducing information from the video disc, the information reproduction time from one side is set to about 60 minutes. Therefore, when movie information about a movie that is set to have a relatively long running time is recorded, a series of movie information, for example,
A situation occurs in which the optical disc is divided into two optical video discs for storage.

Reproduction of information recorded thereon from optical discs, including optical video discs and others, is accomplished using optical disc players. The optical disc player has, as basic components, an optical disc mounted therein, a disc drive unit for rotating the mounted optical disc at a predetermined rotation speed, and a light beam incident on the information recording surface of the rotating optical disc. Obtained from the optical head unit that detects the reflected light beam or transmitted light beam from the optical disc and obtains the read output signal as the detection output, the head drive unit that moves the optical head unit along the information recording surface of the optical disc, and the optical head unit. An information reproduction processing unit for reproducing information based on the read output signal is provided. In addition, in the optical disc player, normally,

A focus servo control system for properly maintaining the focus state at

Under such circumstances, in reproducing information from, for example, two optical video discs recorded by dividing and storing a series of movie information as described above, It is considered that one optical disc player is used and that two optical disc players are used. Then, when one optical disc player is used, first, one of the two optical video discs is mounted in the disc drive section of the optical disc player, and the optical disc player reads the information. Readout of movie information from one of the two optical video discs by the reproduction operation state, and a video signal and an audio signal representing an image and sound of the movie based on the read movie information. Is played. Next, when such reproduction is completed, the other of the two optical video discs is replaced with the other one, and the optical disc player is mounted in the disc drive section, and the optical disc player is in the information reproducing operation state. The reading of the movie information from the other of the two optical video discs, and the reproduction of the video and audio signals representing the images and sounds of the movie based on the read movie information. Will be done.

On the other hand, when two optical disc players are used, two optical video discs are mounted in the disc drive section of each of the two optical disc players. Under such circumstances, first, 2
One of the two optical disc players is in an information reproducing operation state, thereby reading movie information from one of the two optical video discs, and based on the read movie information, The video signal and the audio signal representing the image and sound of the movie are reproduced, and when the reproduction is finished, the other one of the two optical disc players is set to the information reproducing operation state, and accordingly, Reading of the movie information from the other of the optical video discs and reproduction of the video and audio signals representing the images and sounds of the movie based on the read movie information. Under the condition that one of the two optical disc players is in the information reproducing operation state, the video signal and the audio signal reproduced by the one are reproduced and outputted, and the two optical disc players are also reproduced. While the other of the disc players is in the information reproducing operation state, the video signal and the audio signal reproduced by the other one are reproduced and output.

[0007]

When the reproduction is completed, the other one of the two optical disc players is set to the information reproducing operation state, and the video signal and the audio signal reproduced by one of the two optical disc players are reproduced and output. From the state
It is necessary to perform an operation for switching to a state in which the video signal and the audio signal reproduced by the other of the two optical disc players are reproduced and output. Therefore,
Also in this case, the reproduction of the video signal and the audio signal is interrupted while the operation is performed.

As described above, the situation in which the reproduction of the video signal and the audio signal representing a series of images and sounds of a movie is carried out in an interrupted state makes the user of the disc player feel annoyed. As a result, the user of the disc player, who is watching a movie based on the reproduced video signal and audio signal, loses interest.

In view of the above point, the present invention provides a plurality of information recorded by dividing and storing a series of information.
For example, when reproducing information from a recording medium such as an optical disc, information reproduced from a plurality of recording media is

When the reading of the portion is detected, a standby control signal for causing the other device to wait for the information reproducing operation is formed and transmitted to the other device, and thereafter, the recording medium is also transmitted. When the reading of the end portion of the information recorded on the device is detected, a start control signal for causing another device to start the information reproducing operation is formed and transmitted to the other device, and the information is transmitted to the other device. Switching from a state in which the output information signal obtained from the reproduction processing unit is derived to the information signal output unit to a state in which the output information signal from another device through the external signal input unit is derived to the information signal output unit. Becomes operation state can take. At that time, in other devices, the standby state for the information reproducing operation is taken in response to the standby control signal, and the information reproducing operation is started in response to the start control signal. , Is supplied to the external signal input unit.

Therefore, when the information reproducing apparatus according to the present invention is used to reproduce information from a plurality of recording media recorded by dividing and storing a series of information, one of them is used. Is reproduced by the information reproducing apparatus according to the present invention, and the information reproduction from another apparatus is performed by the other apparatus. Output information signal is derived, followed by setting that the output information signal from another device is derived, so that a series of information is divided and stored to record a plurality of recorded information. The information reproduced from the recording medium can be continuously obtained substantially without interruption.
