In the optical disc player using the optical disc, the detailed data display of the optical disc player is performed by utilizing the lead in area data of the optical disc to perform the skip setting function while having the detailed data display even in the stop mode. It relates to a skip setting method.

In general, an optical disc player using an optical disc such as a CD, CDV, LD, etc. uses some of the disc data recorded on the optical disc, and most of the disc data is track number, total time, and remaining time. It is well known that data such as TIME) and frame number are used only in the playback mode and only the total time and the total number of frames are displayed in the stop mode.

As shown in FIG. 5, when the user turns on the power switch (step 50) and inserts an optical disc (step 51), the microprocessor checks whether the door is open (step 52) and closes the door only when it is opened. The master performs the door open / close mode (step 53), and then reads the disk data of the lead-in area data recorded on the innermost circumference of the optical disc through the pickup unit (step 54).

The disc data read out is notified to the outside via the display (step 55), checking whether the other key switch is turned on for the other mode (step 56), and if the other key switch is turned on, the corresponding mode selected by the key switch. (Step 57), if the stop key switch is turned on to select the stop mode (step 58), the disc data is displayed via the display section (step 59).

However, according to the data display method of the conventional optical disc player as described above, various functions are included in the other modes including the play mode, but in the stop mode, only simple functions can be performed in addition to the function of executing the program. However, the display function did not display enough disk data, but only simple content such as total time and total number of frames.

And while most of the keyswitch is used in the stop mode, it is not possible to perform the detailed data check function of the optical disc, and most songs have to be programmed when deleting part of the optical disc during the play mode. The function has disadvantages such that the user has to play the program in a predetermined order by using the number of tracks (or chapter number) of the optical disc or change the program from time to time.

Accordingly, an object of the present invention is to provide a detailed data display method of an optical disc player that has various display functions by adding a detailed data check function of the optical disc.

Another object of the present invention is to provide a skip setting method of an optical disc player in which an undesired part is not played.

To this end, the present invention provides an optical disc player using an optical disc, comprising: a key input unit for recognizing a selection as a user turns on / off mode selection key switches of a power key switch, a play key switch, and a stop key switch; A microprocessor that controls the overall operation according to the processing procedures and conditions stored in the internal program memory according to a user's selection input from an input unit, a door sensor that recognizes an open / closed state of a door and transmits the state to the microprocessor, and the microprocessor A door driver for opening or closing the door under the control of the microprocessor, a slide motor driver for controlling the forward / backward operation of the slide motor for moving the pickup unit in and around the pickup unit under the control of the microprocessor, and under the control of the microprocessor. Adjust the tilt of the pickup unit The tilt motor driving unit controls the tilt motor driving, and transmits the recorded disk data of the optical disk to the microprocessor and stores it in the memory while maintaining a stable state by the tilt motor and the slide motor. This allows the detailed data check of the optical disc and the skip setting.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

User selects the mode selection keys such as power key switch (PW), play key switch (PB), stop key switch (STOP), program mode selection key switch (PRO), set key switch (SET), reversal switch (REV), etc. A key input unit 1 for recognizing a user's option by turning on / off positions, and a processing procedure stored in the internal program memory 3 according to a user's option input through the key input unit 1; A microprocessor 2 for controlling overall operation according to a condition, a door sensor 4 for detecting an opening / closing state of a door (not shown in the drawing) and transmitting the same to the microprocessor 2, and the microprocessor 2 of the microprocessor 2. Under the control, the door driver 5 opens or closes the door and the slide motor 6 follows the pick-up unit 10 in the inner circumferential direction or the outer circumferential direction of the optical disc under the control of the microprocessor 2. Reverse rotation Or a tilt motor driver for controlling the driving of the slide motor driver 7 for controlling while stopping and the tilt motor 8 for tracking the movement of the optical disk while rotating the inclination of the pick-up unit 10. 9) and the slide motor 6 and the tilt motor 8 read the data of all tracks including the innermost lead in area data while the optical disk 11 is stably followed. A pickup unit 10 to be transferred to the processor 2, a memory 12 for storing or outputting data read by the pickup unit 10 under the control of the microprocessor 2, and the microprocessor 2 And the display unit 13 which displays and informs the data recorded in the memory 12 or the read data according to the control.

The detailed data display method of the optical disc player of the present invention configured as described above allows the user to supply power while turning on the power key switch PW of the key input unit 1 in the optical disc player using the optical disc (step 20). 11 is inserted (step 21), the microprocessor 2 checks whether the door is closed through the door sensor 4 (step 22), and when opened, closes the door through the door driver 5 ( Step 23).

Next, the pickup unit 10 moves to the lead-in area data at the innermost circumference of the optical disc 11 while driving the slide motor 6 through the slide driver 7 (step 24), and the tilt motor driver 9 The tilt motor 8 is controlled to move inclined according to the shaking during the rotation of the optical disc 11 while controlling the tilt motor 8 (step 25), and the recorded data of the lead-in area data of the optical disc 11 is picked up by the pickup unit 10. Read through (step 26), and store in memory 12 (step 27).

In the microprocessor 2, the total number of tracks 3 and the total playing time (34 minutes 25 seconds) are displayed on the display unit 13 as shown in FIG. 3 (step 28). Or if the user requests the following detailed data while using the existing keyswitch twice (step 29), the number of tracks (1), (2), (3) and the playing time of each track (11 minutes 45 seconds) , (12 minutes 27 seconds), (10 minutes 33 seconds), the total number of tracks (3) and the total playing time (34 minutes 25 seconds) are displayed in turn (step 30), and then other keyswitches (PB, etc.) Check if it is on (step 31), and if so, switch to the corresponding mode (step 32), if not, check again whether the user has selected the stop mode with the STOP key switch (STOP) (step 33).
