Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a recording track on which audio information and the like can be recorded, and a control track on which control data corresponding to data recorded on the recording track can be recorded. The present invention relates to a playback skip setting device in an information recording device that performs a recording operation on a recording medium on which data once recorded on each of the control tracks cannot be rewritten.

[0002]

2. Description of the Related Art An information recording apparatus for optically recording audio information using a recording medium such as a CD-R or a DVD-R capable of recording only once has been widely used. The recording of information to is started by the operation of the recording instruction operation button, and one independent recording track is created by ending the recording operation by operating an operation instruction button other than the recording instruction operation button, for example, the stop instruction button. It is formed.

Immediately after recording on such a recording track, control data such as address information, track number data, and track length data corresponding to the data recorded on the recording track are recorded on the control track. .

[0004] During the recording started by the operation of the recording command operation button, the operation of the "operation button for stopping the recording operation" such as the stop button is always effective. If the recording operation is stopped during the time, an extremely short recording track is formed. Such an extremely short recording track is generally based on a recording failure or is a useless recording track. Therefore, when such a recording track is created, the recording medium is not recorded. By nature,
That is, the track cannot be erased due to the characteristic that recording can be performed only once.

[0005] For this reason, during playback, after setting the operation mode of the playback device to the skip setting mode and inputting the track number to be skipped, the playback skip registration is performed so that the recording track for a very short time is not played back. After that, skip playback is performed.

[0006]

In a conventional information recording apparatus of this type, a recording track for a very short time which has been created due to a recording failure or the like cannot be erased. Unnecessary track playback is performed, giving the user an unpleasant sensation, and registration for performing “skip playback” to prevent this playback must be performed by a complicated manual operation. However, there is a problem that the user is forced to perform complicated operations.

[0007] Therefore, an object of the present invention is to provide a reproducing apparatus with a recording medium having an extremely short recording track which has been created due to recording failure or the like, without performing any complicated operation manually. Another object of the present invention is to provide a "playback skip setting device in an information recording device" that can automatically perform skip playback.

[0008]

In order to solve the above-mentioned problems, a reproduction skip setting device in an information recording apparatus according to the present invention employs the following characteristic configuration.

(1) It has a recording track on which audio information and the like can be recorded and a control track on which control data corresponding to data recorded on the recording track can be recorded.

Control means for recording such reproduction skip control data on the control track of the recording medium. Reproduction skip setting device in the information recording apparatus comprising and.

(2) A reproduction skip setting device in an information recording device, wherein the time setting means of (1) is configured to be able to be fixed to a preset time setting value.

(3) A reproduction skip setting device in an information recording device, wherein the time setting means of (1) is configured to be capable of changing a preset time setting value.

(4) The reproduction skip setting in the information recording apparatus, wherein the timer means or the control means of (1) arbitrarily prohibits the operation and includes prohibition control means which can arbitrarily release the prohibition. apparatus.

(5) The prohibition control means of (4) is a means for disabling the means for inactivating the information recording on the recording track when a recording mute operation command for forming a silent recording track for a predetermined short time is issued. A playback skip setting device in an information recording device configured to include.

(6) A reproduction skip setting device in an information recording device in which the recording medium according to any one of (1) to (5) is constituted by an optical disk such as a CD-R or a DVD-R.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, a CPU 1 for integrally controlling the entire information recording apparatus is provided, and a recording / reproducing unit 2 is connected to the CPU 1, for example, a CD-R.
And information can be reproduced.

The operation keys 3 connected to the CPU 1 are used to give operation commands for playback, stop, pause, fast forward playback, fast forward playback, and recording.
The editing key 4 connected to U1 is a key for giving an instruction to reproduce only a specific track when reproducing a recording track.

The CPU 1 is connected to a skip determination unit 5, a timer 6, and a timer time setting unit 7, and the operation keys 3
When information recording on the recording track is started by the button operation of
The time setting means for inputting the time setting value of the timer 6 is constituted by the timer second time setting section 7.

When the recording operation is completed by operating an operation command button other than the recording command operation button of the operation keys 3 before the time set value is reached after the time measurement is started by the timer 6, the recording is stopped. Control means for sending reproduction skip control data for skipping reproduction on a track to the recording / reproducing unit 2 and recording it on a recording medium is constituted by the skip determining unit 5.

Therefore, when the recording operation is started as in step S1 of the flowchart shown in FIG. 2, it is determined in the next step S2 that "recording operation stop key is input?" It is determined whether or not a key other than the recording key is operated, and in the case of Yes, the process proceeds to step S7 to execute a recording operation.

In step S7, as shown in detail in the flowchart shown in FIG. 3, first, in step S8, it is determined whether "recording timer is operating", that is, whether timer 6 is operating is determined. If the operation is in progress (in the case of Yes), the process proceeds to step S9 to record the data recorded on the recording track, that is, the skip ID (control data) corresponding to the very short track within the time set by the timer 6. The information is recorded on the control track of the medium, the track is changed in the next step S10, the timer 6 is initialized (reset) in the next step S11, and the timer starts to return to step S2 in FIG.

On the other hand, if it is determined in step S8 that "recording timer is operating", that is, whether timer 6 is operating or not, if it is not operating (No), control proceeds to step S12. And the process returns to step S2 in FIG.

Returning to FIG. 2, the determination of "recording operation stop key input?" In step S2, that is, whether or not any of the operation keys 3 other than the recording key is operated is determined, and the result is No. If so, proceed to step S3,
In the same manner as in step S2, a determination of "recording operation stop key input?" Is made. In the case of No, the process returns to step S2.

Step S4 is to judge "recording timer is operating", that is, to judge whether or not timer 6 is operating. If it is not operating (No), step S6 is executed. And the recording operation ends.

If it is determined in step S4 that "recording timer is operating", that is, if the timer 6 is operating (Yes), the process proceeds to step S5. . In this step S5, the data recorded on the recording track, that is, the skip ID (control data) corresponding to the very short track within the time set by the timer 6, is recorded on the control track of the recording medium. And the recording operation ends.

The above operation is performed by the timer second setting unit 7.
The setting operation by the timer time setting unit 7 will be described next with reference to the flowchart shown in FIG.

In the flowchart shown in FIG. 4, when the setting of the auto skip track is started in step S13, first, in step S14, it is determined "validate the setting of the auto skip track?"
If it is o, the process jumps to step S18 to forcibly end the setting.

Such a forced termination is constituted by arbitrarily prohibiting the operation of the above-mentioned "timer means or control means" and including prohibition control means capable of arbitrarily releasing the prohibition. This is because the prohibition control means is configured to include a means for disabling when a recording mute operation command for forming a silent recording track for a predetermined short period of time for information recording on the recording track is issued.

If Yes in step S14, that is, if the prohibiting means is not working, the flow advances to the next step S15, where the setting by the timer second setting unit 7 is started. It is determined whether or not to change the setting. If No, the process jumps to the previous step S18 to forcibly end the setting. If Yes in step S16, the process proceeds to step S17, where the timer The timer time is set to an arbitrary value by the setting unit 7,
Thereafter, the process proceeds to step S18 to complete a series of setting operations.

Therefore, when recording is performed on the recording medium, the timer 6 is provided to measure the time from the start of recording, and when a track change is performed during recording, the timer is newly started. When a process for stopping the recording operation is performed while the timer 6 is operating, a skip ID (control data) is automatically added to the recording track being counted.
Is recorded on the control track.

Whether or not to record these skip IDs (control data) on the control track can be arbitrarily selected by the user by providing a prohibition means. The set second time in 6 can be set to an arbitrary value by the timer second time setting unit 7.

The configuration for setting the timer time set by the timer time setting unit 7 can be fixed to a preset time set value or can be varied. Or may be obtained.

[0032]

As is apparent from the above description, the reproduction skip setting device in the information recording device according to the present invention can be used when reproducing a very short recording track created by a recording failure or the like by a reproducing device. Skip playback can be performed automatically, and comfortable playback can be performed without forcing the user to perform complicated operations.

Therefore, according to the present invention, when a recording medium having an extremely short recording track created due to a recording failure or the like is set in a reproducing device, no complicated operation is performed manually. In addition, it is possible to provide a playback skip setting device in an information recording device capable of automatically performing skip playback.
