DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk recording / reproducing apparatus, and more particularly to an optical disk recording / reproducing apparatus capable of recording track numbers quickly.

[0002]

2. Description of the Related Art For example, in an optical disk recording / reproducing apparatus such as an MD (mini-disc) recording / reproducing apparatus, a recording area of an optical disk is defined by a track number TNO called a movement number. Search is easy. The function of inserting and erasing track numbers is often built in the apparatus, and can be inserted and erased at an arbitrary location by operating a user's insert key or erase key.

For example, after recording live music on an optical disk using the above-described optical disk recording / reproducing apparatus, a user operates an insertion key to record a track number between each music piece or at a desired position. it can. Here, the key
If the operation timing is shifted and the track number cannot be recorded at the desired position, delete the recorded track number by operating the erase key and then record the track number at the new correct position. Will do.

In a conventional optical disk recording / reproducing apparatus, when a track number is erased, a track number address immediately before the erased track number is searched, and a reproduction pause state is set at that address position.

[0005]

As described above, in the conventional optical disk recording / reproducing apparatus, when a track number is erased, the apparatus returns to a track number position immediately before the erased track number and enters a reproduction pause state. Therefore, if a new track number is to be inserted and recorded at an address near the erased track number, a fast-forward operation must be performed to the adjacent address to be recorded. However, there was a problem in terms of operability.

It is an object of the present invention to provide an optical disk recording / reproducing apparatus capable of quickly re-recording a track number by a simple operation.

[0007]

In order to solve the above-mentioned problems, an optical disk recording / reproducing apparatus according to the present invention is directed to an optical disk recording / reproducing apparatus capable of inputting / erasing a track number to / from an optical disk by operating an operation unit. In response to a track number input / erase operation, a search is made for an address position that is a predetermined time earlier than the address of the input / erase timing, and pauses at the search position.

[0008]

According to the present invention, inputting and erasing of a track number to an optical disk are performed in response to an operation, and a pause is performed at an address position a predetermined time earlier than an address of an input and erasing timing at a previous address position (reproduction pause state). ).

[0009]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram for explaining a basic operation of an optical disk recording / reproducing apparatus according to the present invention.

In FIG. 1, for example, songs 1, 2, and 3 are recorded in areas # 1, # 2, and # 3 of the recording area of the optical disk, and a track number TNO . 1, TNO. 2 and TNO. 3 is recorded. At this time, the track number TNO. 1 and TNO.
3 is recorded at the correct address position, but the track number TNO. 2 is not correctly recorded, in the present embodiment, the currently recorded track number TN
O. After erasing 2, control is performed to return to the previous address position for a predetermined period of time t (for example, for 3 seconds) and to enter the reproduction pause state.

That is, in the prior art, an address position for recording is set again by an operation such as a see-through operation after returning to an address position one track number earlier, whereas in the present embodiment, the address position is returned for a few seconds. Therefore, the return to the recording address position is immediately performed again.

FIG. 2 is a block diagram showing the configuration of an optical disk recording / reproducing apparatus according to the present invention. The recordable / reproducible optical disk 11 is driven to rotate by a disk motor 12, and a recording signal from a recording / reproduction signal processing unit 15 is recorded via an optical pickup 13 and a magnetic field modulation head 14.
The recording signal from the input terminal 18 is transmitted to the A / D converter 16
Is converted into a digital signal by the recording / reproducing signal processing unit 1
5 sent out. This recording can be overwritten by a magnetic field modulation type due to overheating by the optical pickup 13 and magnetization of the recording layer of the optical disk 11 by the magnetic field modulation head 14.

In reproduction, a signal read through the optical pickup 13 is reproduced by a recording / reproduction signal processing unit 15, converted into an analog signal by a D / A converter 17, and output. The recording / reproduction signal processing unit 15 performs servo control on the disk motor 12 and the optical pickup 13.

The system controller 19 performs overall control of the apparatus, and performs system control based on key information from the key operation unit 20. The display unit 21 displays various information such as the operation state of the device. As shown in FIG. 3, the key operation section 20 includes an insert (INSERT) key 20A, a delete (CANCEL) key 20B, and a track delete (TRACK DELETE) key 20C.

Referring to FIG. 1, the operation of this embodiment will be described below. When the optical disk 11 is reproduced and the track number (TNO) is input by pressing the insert key 20A at an arbitrary position (timing) where the track number is desired to be recorded, the system controller 19 controls the predetermined position from the input arbitrary position. The retroactive address is calculated for the time (3 seconds), the address is searched, and a reproduction pause state is set. The input address of the track number is written into the RAM incorporated in the system controller 19, and is written as information in the U-TOC.

When erasing a track number (for example, track number TNO.2 in FIG. 1), the track number TNO. During the reproduction of No. 2, the erase key 20B is pressed.
At this time, the system controller 19 sends the TNO. For example, a three-second retroactive address is calculated from the address where the number 2 has been found, and the address is searched for, and a reproduction pause state is set. Thereafter, if a new track number is inserted and recorded while reproducing, rapid processing becomes possible. The erased TNO. The address data of No. 2 is erased in the RAM of the system controller 19 and is reflected in the U-TOC information. At this time, the track number is displayed on the display unit 21 and is visible to the user.

There may be provided a function mode for executing the operation of this embodiment and a function mode for executing the conventional operation, and the function mode selected by the user may be executed.

As described above, according to the present embodiment, when a track number is inserted at an arbitrary position in the recording area of the optical disk, a search is made to the address position for three seconds (predetermined time) and the reproduction pause state is set. By releasing the pause, the timing of the input track number can be confirmed. If the input timing has failed (when the timing is not the desired timing), the track number is erased to search for an address position three seconds before the address position of the erased track number and reproduce it. It enters a pause state. Then, the pause can be canceled and the track number can be quickly inserted again without going through the fast-forward or fast-return operation.

[0019]

As described above, according to the optical disk recording / reproducing apparatus of the present invention, a track number can be quickly recorded at a desired recording position by a simple operation.
