It is a key switch part consisting of etc.

As shown in FIG. 7, the editing calculation unit 6 calculates the playback time of each song number to be played from the TOC data storage unit 9 that stores the TOC information detected by the signal detection unit and the TOC information, and further calculates the playback time of each song number to be played. Playback time calculation unit 10 for calculating the total
and editing time input means 11 for inputting the editing time for editing the songs to be recorded on the A side and B side of the tape when recording information recorded on a disk on a magnetic recording tape or the like.
and an editing time storage unit 12 that stores the input editing time.
and a subtraction means 13 which calculates the editing time 172 and subtracts the playback time obtained from the playback time calculating section 10 to find the remaining time, and a value obtained from the subtraction means during automatic editing is judged and edited. A playback song setting section 14 sets the song to be played within a certain time, an A-side playback storage section 8 and a B-side playback song storage section 8' store the determined songs. An arbitrary song storage means 7 for storing any song, and an arbitrary number of deletion means 15 for deleting an arbitrary song from the storage section.
It is composed of.

With the above configuration, control as shown in the flowchart of FIG. 9 was performed.

That is, in step 1, it is determined whether the edit designation key 5a has been pressed, and if it has been pressed, the process moves to step 2, and if it has not been pressed, the process ends. In step 2, input of the editing time using the editing time input key 5b is accepted. In step 3, it is determined whether an editing time has been input. If there is an input b<, the process moves to step 4; if there is no input, the process returns to step 2, and steps 2 to 3 are repeated until there is an input.

In step 4, the playback song setting section 14 calculates the playback time in order from the first song on the disc, and each time the number of songs increases, the total playback time and the editing time of 172 are subtracted by the means 13.
While comparing the results, set the songs to be played on side A, and set the songs to be played on side B in the same manner for the remaining songs. In step 5, it is determined whether the subsequent operation is to edit side A or side B by inputting the A/B switching key 5e, and if it is side A, proceed to step 6, and if side B, proceed to step Move on to 7. In step 6, the display etc. are set to the A-side editing mode. In step 7, the display and the like are similarly set to the B-side editing mode. In step 8, it is determined whether there is an input to the arbitrary song memory key 5C, and if there is an input, step 9
If there is no input, the process moves to step 11. In step 9, the input specified song is additionally stored in the playback song storage units 8 and 8''. In step 10, the playback time when additionally stored is determined by the playback time calculation unit 10, and the subtraction unit 13
The remaining time is determined by and displayed on the display section 4.

In step 11, it is determined whether or not the delete key 5d has been pressed any number of times. If it has been pressed, the process moves to step 12; if it has not been pressed, the process moves to step 14. In step 12, the input designated music piece is searched out from the playback music storage units 8 and 8° and deleted. In step 13, the playback time at the time of deletion is determined by the playback time calculation unit 10, the remaining time is determined by the subtraction unit 13, and this is displayed on the display unit 4. In step 14, it is determined whether the editing is finished, and if it is finished, the process is finished, and if not, the process returns to step 5 and steps 5 to 14 are repeated until the editing is finished.

Problems to be Solved by the Invention However, in the configuration of the conventional example described above, since the automatic editing function sets the songs in order starting from the first song on the disc, the editing time (tape cassette (e.g. the length of a magnetic tape), it will not be possible to record all the songs recorded on the disc, and for example,
If the user's favorite song is recorded towards the end of the disc, it will not be recorded by automatic editing, so after automatic editing,
This method has the disadvantage that it is very troublesome as it requires an operation for replacing songs using an arbitrary storage key and an arbitrary song deletion key.

It has a request song search section 38 that searches for a song number stored in the , and a remaining time storage section 37 .

The operation of the optical disc reproducing apparatus of the present invention configured as described above will be explained using the flowchart shown in FIG. Incidentally, steps 2 to 14 are the same operations as in the conventional example, and their explanations will be omitted.

First, in step l, it is determined whether or not the edit designation key 25a has been pressed, and if it has been pressed, the process proceeds to step 15.In step 15, it is determined whether or not the request key 25f has been pressed, and if it has not been pressed, step The process advances to step 2, and if the button has been pressed, the process proceeds to step 16, where the requested music is accepted.

For example, the user selects and inputs the song number that the user would like to record using the request song setting means 40 such as an IO key, and stores it in the request song storage section 39.

The song number is also stored in the A-side playback song storage section 28. In this state, the track number array display 24a on the display unit 24 is the fifth track number.
As shown in the figure, if song number 2 is specified, all lights are turned on and only 2 is turned on repeatedly, and when song numbers 5, 7.8 are input in the same way, they are stored in the requested song storage section 39. At the same time, the screen is displayed as shown in FIG. 5 (3).

Then, when the process advances to step 17, an editing time input is accepted. For example, the length of the cassette tape used by the editing time input means 31 (60 minutes for a C60 tape, 60 minutes for a C45 tape,
(If the time is 45 minutes or any other time can be set arbitrarily), the editing time is inputted and stored in the editing time storage section 32.

Then, in step 18, it is determined whether or not the editing time has been input, and if it has been input, the process proceeds to step 19 and calculates the remaining time. The remaining time is calculated based on the desired song number input by the user stored in the A-side playback storage section and the playback time data corresponding to each song number from the TOC data storage section 29. The remaining time after inputting the desired song is calculated by calculating the playback time of the desired song in the playback time calculation section 30 and subtracting the calculated time from the editing time stored in the editing time storage section 32 by the subtraction means 33. The remaining time is stored in the remaining time storage section 37.

Then, the process proceeds to step 20, in which edited songs other than the requested songs are set with the remaining time.

That is, the data in the remaining time storage section 37 is sent to the editing time storage section 32, and within this remaining time, the playback song setting section 34 is used to search for the requested song by the requested song search section 38, and the requested song is searched for other than the requested song. It performs automatic editing.

As described above, according to this embodiment, □ By setting the desired song number in advance by the user using the request song setting means 40, the desired song can be recorded with priority, and other than the desired song in the remaining time. This enables automatic editing of files.
