The present invention relates to an operation control method of an optical disc device, and more particularly, to an operation control method of an optical disc device for recovering to a previous operation state even when the optical disc is removed from the optical disc device and then remounted. .

In general, an optical disc apparatus is a device for reproducing data recorded on an optical disc or recording user data on an optical disc. Such an optical disk device is an information storage medium for recording and storing audio and video data. As optical disks such as CDs and DVDs are widely used and commercialized, their functions are expanded in various ways.

In recent years, standardization on high-density optical discs such as Blu-ray Disc (BD) or High-Density Digital Versatile Disc (HD-DVD), which can store high-quality video and high-quality audio data for a long time. This rapid is moving forward. Accordingly, in the future, it is expected that an optical disc device capable of recording or reproducing the high density optical disc will be developed and commercialized.

Such an optical disc apparatus stores information on a data recording stop position or a reproduction stop position in an internal memory when a recording or reproduction operation is interrupted by a user during a process of recording or playing data on an optical disc. In addition, when power is supplied to the optical disc device, a function of continuously recording or reproducing from the position at which the previous recording was stopped or the position at which reproduction was stopped is provided by using the information stored in the memory.

However, the above function is implemented so that the user can select a recording or playback start position only when the optical disc is not removed from the optical disc device. This is because the conventional optical disk device is determined to replace a new disk when the optical disk is removed from the optical disk device, so that the information on the previously used disk is deleted from the memory.

However, there is often a case in which the optical disc is removed from the optical disc apparatus and then reinserted to re-use the previously used portion. However, according to the conventional method, since the information stored in the memory is deleted when the optical disk is removed from the optical disk device, there is a problem that the state before power off or the operation state before the optical disk is removed from the optical disk device cannot be recovered.

Further, according to the conventional method, even when the same optical disk is reinserted, it is determined that a new optical disk is mounted. Therefore, conventionally, even when the previously used optical disc is reinserted, it is troublesome to set the internal variables of the optical disc device to a recordable or reproducible state, and thus, there is a problem that the recording or reproducing operation cannot be performed quickly. Occurs.

Therefore, the present invention was created to solve the above problems, and provides a method for improving the user's convenience by allowing the optical disk to be restored to its previous operation even when the optical disk is removed from the optical disk device and then remounted. To provide.

In order to solve the above technical problem, the operation control method of the optical disk device according to the present invention, when the optical disk is inserted and seated in the optical disk device, the identification information and operation state information for the previously recorded or reproduced optical disks Determining whether the same identification information as that of the inserted optical disc is present in the stored memory; Reading operation state information corresponding to the inserted seated optical disc from the memory when the same identification information as that of the inserted seated optical disc exists in the memory; And recovering, by the optical disc device, the optical disc to a previous operation state by using the read operation state information.

If the same identification information as the identification information of the inserted optical disc does not exist in the memory, determining that a new optical disc is inserted and mounted, and performing a disc recognition operation.

Preferably, the method further includes providing a menu screen on which the user can select whether to restore the previous operation state before restoring the optical disc to the previous operation state by using the operation state information read from the memory.

The menu screen may include a menu item for allowing the user to select a playback start position or a recording start position.

The operation state information stored in the memory is information detected from the optical disk device in response to the generation of a command to stop the operation of the optical disk device.

The command for stopping the operation of the optical disk device is any one of a recording stop command, a playback stop command, a pause command, and a power off command.

And the operation state information includes internal variable setting information, previous recording stop position information, and previous reproduction stop position information of the optical disc device.

Preferably, the operation state information further comprises a user setting information.

The identification information may be a volume name of an optical disc.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail. However, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

1 is a block diagram schematically showing an optical disk device according to a preferred embodiment of the present invention.

As shown in FIG. 1, the optical disk apparatus 100 according to the present invention includes a pickup unit 110, an RF signal processor 120, a digital signal processor 130, and a servo controller 140. The servo driver 150 includes a spindle motor 160, a flash memory 170, an EEPROM 180, and a system controller 190.

First, the optical disk device 100 according to the present invention is a device for recording data on the optical disk 100a or reproducing data recorded on the optical disk 100a. The optical disc apparatus 100 applicable to the present invention is a CD (Compact Disc Player) or DVDP (Digital Versatile Disc) that can be widely used and commercialized, such as a CD (Compact Disc), a DVD (Digital Versatile Disc), and can record or play an optical disc. Player), DVDR (Digital Versatile Disc Recorder), and the like.

In addition, as the standardization work of high density optical discs such as BD (Blu-ray Disc) and HD-DVD (High Density-DVD) is rapidly progressing, it is a matter of course that an apparatus capable of recording or reproducing this high density optical disc is applicable.

The pickup unit 110 records a predetermined signal on the optical disc 100a or reads out a signal recorded on the optical disc 100a and converts the signal into an RF signal.

The RF signal processing unit 120 processes and outputs an RF signal output from the pickup unit 110 into an amplified and binary signal.

In addition, the RF signal processing unit 120 generates a focusing error (FE) signal for focusing servo and a tracking error (TE: tracking error) signal for tracking servo and provides the result to the servo controller 140.

The digital signal processor (DSP) 130 demodulates and corrects the signal processed by the RF signal processor 120 to a desired signal value, or records a recording target signal in a format that can be recorded on the optical disc 100a. Convert and output

The servo controller 140 controls the driving of the servo driver 150 based on the FE signal and the TE signal output from the RF signal processor 120.

The servo driver 150 generates a driving voltage for driving the spindle motor 160 and the pickup 110 under the control of the servo controller 140 and supplies the generated driving voltage to the spindle motor 160 and the pickup 110. .

The spindle motor 160 rotates the optical disc 100a in the forward or reverse direction according to a predetermined driving voltage supplied from the servo driver 150.

The flash memory 170 stores various control programs necessary for performing the operation of the system controller 190.

The EEPROM 180 separates the operation state information including the internal variable information, the user setting information, the file system information, the previous recording stop position information, or the previous playback stop position information set in the optical disc device 100 for each disc. Save it.

The internal variable setting information is information set based on disc information (DI) read out from the optical disc 100a through a disc recognition process and means information set for a recording or reproducing operation.

In addition, the user setting information refers to information set by the user in relation to video or audio.

On the other hand, data recorded on the optical disc 100a is managed by a specific method, which is called a file system of the optical disc. In the file system, not only the attribute information of each file and the recorded position on disk, but also information for overall file management such as the relationship between the files are recorded. As described above, the EEPROM 180 stores the operation state information on each of the previously recorded or reproduced optical discs based on the identification information (eg, the volume name) corresponding to each of the optical discs.

The system controller 190 controls the overall operation of the optical disk device 100 according to a control program stored in the flash memory 170. For example, if the recording or reproducing operation of the optical disc apparatus 100 is stopped in response to a command to stop the operation of the optical disc apparatus 100, the system controller 190 causes the optical disc apparatus at the time when the recording or reproducing operation is stopped. The operation state information of 100 is detected and stored in the EEPROM 180. In the above, the command to stop the operation of the optical disc apparatus 100 includes a recording stop command, a reproduction stop command, a pause command, or a power off command. In addition, as described above, the operation state information may be implemented not only at the time when the recording or reproducing operation is stopped, but also periodically stored at each time point set by the user.

The system controller 190 detects the insertion of the optical disk 100a into a tray (not shown) provided in the optical disk apparatus 100, that is, whenever an open / close of the tray is detected, the EEPROM ( It is determined whether the same identification information as that of the optical disc 100a currently inserted and seated exists. If it is determined that the same identification information as that of the optical disc 100a currently inserted and seated in the EEPROM 180 exists, the optical disc apparatus 100 is transferred using the operation state information stored in the EEPROM 180. Restore to operation.

On the other hand, if it is determined that the same identification information as that of the optical disc 100a currently inserted and seated in the EEPROM 180 does not exist, the system controller 190 inserts and mounts the new optical disc 100a. It is determined that the disk recognition operation.

2 is a flowchart illustrating an operation control method of an optical disk device according to an embodiment of the present invention.

1 and 2, it is determined whether the optical disk 100a is inserted and seated in a tray provided in the optical disk apparatus 100 (S210).

If it is determined in step S210 that the optical disc 100a is inserted and seated in the tray provided in the optical disc apparatus 100 (S210), the system controller 190 identifies identification information (volume name) of the optical disc 100a currently inserted and seated. The servo control unit 140 is controlled to read (S220).

When the identification information on the optical disk 100a currently inserted and seated is read through the step S220, the system controller 190 checks the EEPROM 180 to read the optical disk 100a read in the EEPROM 180 in step 220. It is determined whether the same identification information as the identification information of (S230, S240).

If it is determined in step S240 that the same identification information as that of the optical disc 100a currently inserted and seated in the EEPROM 180 does not exist, the system controller 190 replaces the currently inserted optical disc 100a with a new one. The disk recognition operation is performed by determining that the optical disk is in operation S250.

On the other hand, if it is determined in step S240 that the same identification information as the identification information of the optical disk 100a currently inserted and seated in the EEPROM 180 exists, the system control unit 190 controls the currently inserted optical disk 100a. Judging by the previously used optical disk. In this case, the system controller 190 provides a menu screen from which the user can select whether to recover to the previous operation state (S260).

The system controller 190 determines whether the recovery to the previous operation state is selected through the menu screen (S270).

If it is determined in step S270 that the recovery to the previous operation state is selected (S270), the system controller 190 restores the optical disk device 100 to the previous operation state by using the operation state information stored in the EEPROM 180. (S280). As a result, the optical disc apparatus 100 is restored to the operation state at the time of stopping the previous recording or reproduction.

On the other hand, when the recovery to the previous operation state is selected, the system controller 190 searches the EEPROM 180 to determine whether the previous play stop position information or the record stop position information is included in the operation state information.

In addition, when the determination result includes the information on the previous playback stop position or the recording stop position in the operation state information, the menu screen provides a menu item for the user to select the playback start position or the recording start position. Therefore, even when the optical disc 100a is restored to the previous operation state, the optical disc 100a can be played from the previous stop position or from the beginning, according to the user's selection.

As described above, according to the present invention, when the conventional optical disc 100a is removed from the optical disc device 100 and then remounted, it is determined that the optical disc 100a is replaced with a new disc, thereby performing the disc recognition operation, thereby speeding up the recording or reproducing operation. You can solve the problem that you can not perform.

In the above description, only the case where the operation of recording or reproducing data on the optical disc 100a is stopped by the user command is not limited thereto. In other words, even when the power supply is forcibly cut off due to a power failure, the controller 120 stores the operation state information before power off in the EEPROM 180. When power is supplied to the optical disk device 100, the optical disk device 100 may be restored to an operation state before power off using the information stored in the EEPROM 180, thereby providing convenience to the user. Of course.

As described so far, according to the optical disc recording apparatus and recording method according to the present invention, information stored in the EEPROM is stored even when the optical disc is removed from the optical disc apparatus. Therefore, even when the optical disc is removed from the optical disc apparatus and then remounted, the previous state can be restored.

In addition, according to the present invention, whenever an optical disc is inserted and seated in an optical disc device, it is determined whether to perform a disc recognition operation by comparing the identification information read from the inserted optical disc with the identification information stored in the EEPROM. That is, according to the present invention, when the optical disk is inserted and seated in the optical disk device, it is determined whether the same identification information as the identification information read from the optical disk currently inserted and seated in the EEPROM exists and the identification information read from the optical disk currently inserted and seated in the EPROM. If the same identification information as is present, the internal variables of the optical disk device are set to be in a state capable of recording or reproducing by using the information stored in the EEPROM. Therefore, according to the present invention, it is possible to quickly perform a data recording or reproducing operation for the optical disc.
