Referring to FIG. 1, an optical disc recording / reproducing apparatus includes a key input unit 110, a microcomputer 120, a playback and recording signal processing unit 130, a disk check unit 140, a disk loader unit 150, and remaining capacity storage. The unit 160, the RFID reading module 170, and the display unit 180 are included. Here, the optical disk 200 loaded in the disk loader unit 150 is provided with an RF tag 202 having a unique ID, that is, an RFID of the optical disk 200, as shown in FIG.

The key input unit 110 includes a plurality of keys for selecting data, setting a recording and reproducing mode, and a key for driving the RFID reading module 170, and supplies a key signal corresponding to the manipulated key to the microcomputer 120. To pass.

The microcomputer 120 reads and reproduces or records data from the optical disc 200 as shown in FIG. 2 loaded in the disc loader unit 150 in response to the key signal of the key input unit 110.

That is, the microcomputer 120 performs a recording mode to control the recording of data input through the playback and recording signal processing unit 130, and after completing the recording of the data, the microcomputer 120 controls the disk check unit 140 to control the optical disk ( In addition to reading the RFID recorded in the RF tag 202 in the 200, the remaining capacity of the optical disc 200 is checked after data recording.

The microcomputer 120 receives the RFID and the remaining capacity of the optical disk 200 from the disk checker 140 and records the same in the remaining capacity table 160. The type of the optical disk 200, that is, the rewritable disk or Information such as information on whether the disc can be recorded once, recordable time information, or the like is recorded in the disc information table 160.

The playback and recording signal processing unit 150 records data in the optical disk 200 loaded in the disk loader unit 150 in the recording mode under the control of the microcomputer 120, and in the disk loader unit 150 in the playback mode. Data is read from the loaded optical disc 200 and reproduced.

The RFID reading module 170 reads an RFID from an RF tag in an optical disk located within a predetermined distance and provides the RFID to the microcomputer 120, and the microcomputer 120 provides RFID and disk information provided from the RFID reading module 170. By comparing the data recorded in the table 160, it is determined whether the information on any optical disc, that is, the remaining capacity of the arbitrary optical disc, or whether it is a recordable disc, is displayed on the display unit 180.

At this time, the microcomputer 120 displays a predetermined message on the display unit 180 when the RFIID for any optical disk is not recorded in the disk information table 160.

The display unit 180 is a VFD (Vaccum Fluorescent Display) that is easy to display in multiple colors and has excellent visibility by emitting light.

A process of providing optical disk information by the optical disk recording / reproducing apparatus having the above configuration will be described with reference to FIG.

3 is a flowchart illustrating a process of providing information of an optical disc by an optical disc recording / reproducing apparatus according to the present invention.

Referring to FIG. 3, first, the optical disc 200 is loaded into the disc loader unit 150, and then the optical disc recording / reproducing apparatus enters a standby state (S300), and receives data from the key input unit 110 in the standby state. As a key signal corresponding to a key for recording is applied (S302), the microcomputer 120 controls the playback and recording signal processing unit 130 to output data input from the outside to the disk loader 150. 200) (S304).

When the data recording is completed in step S304 (S306), the microcomputer 120 controls the disk check unit 140 to the RF tag 202 in the optical disk 200 loaded in the disk loader unit 150. In addition to reading the RFID of the set optical disk 200, information such as the type of the optical disk 200 and the remaining capacity of the optical disk 200 is extracted, and the recordable time information is calculated based on the extracted remaining capacity ( S308).

The microcomputer 120 records the information extracted by the disk checker 140 in the disk information table 160 and then unloads the optical disk 200 loaded in the disk loader 150 to the outside (S310). In this case, when the RFID of the optical disk 200 extracted by the disk checker 140 exists in the disk information table 160, the microcomputer 120 uses the information extracted by the disk checker 140 to display the disk information table. The information corresponding to the RFID of the optical disc 200 stored in the 160 is updated.

The process of checking the information on the optical disc 200 in which data is recorded through the above process without loading the optical disc 200 in the disk loader 150 is as follows.

First, the user places the optical disc 200 within a predetermined distance of the optical disc recording / reproducing apparatus, and then manipulates any key in the key input unit 110, that is, a key for reading information of the optical disc 200. In operation S312, the microcomputer 120 receives the key signal corresponding to the key to drive the RFID reading module 170 to read the RFID set in the RF tag 202 of the optical disk 200 (S314).

Thereafter, the microcomputer 120 compares the RFID provided from the RFID reading module 170 with the disk information table 160 to determine whether the information of the optical disk 200 is stored in the disk information table 160 (S316). ).

As a result of the determination in step S316, when the information of the optical disk 200 is present in the disk information table 160, the microcomputer 120 may store the information of the optical disk 200, that is, the remaining capacity of the optical disk 200 and the recordable time. Information such as an optical disc type is extracted from the disc information table 160 and displayed on the display unit 180 (S318).

As a result of the determination in step S316, when the information of the optical disk 200 does not exist in the disk information table 160, the microcomputer 120 may not display a predetermined message, for example, "the information about the optical disk 200 exists." Does not "display on the display unit 180 (S320).

According to the present invention, after recording data using the RF tag 202 attached to the optical disk 200, the information of the optical disk 200 corresponding to the RFID of the optical disk 200 is stored in the disk information table 160. By providing the information of any optical disk adjacent to the optical disk recording / reproducing apparatus based on the information stored in the disk information table 160, the information of the optical disk can be read without loading the optical disk.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

As described above, the present invention stores the information of the optical disk corresponding to the RFID of the RF tag in the disk information table after data recording using the RF tag attached to the optical disk, and based on the information stored in the disk information table By providing information about any optical disk adjacent to the recording / reproducing apparatus, the information of the optical disk can be read without loading the optical disk, so that the user's convenience can be enhanced.
