BACKGROUND OF THE INVENTION
The present invention relates to an optical disc recording apparatus having a printing function and a control program therefor.
[0002]
[Prior art]
Conventionally, in the case of performing label printing for displaying recorded contents in an optical disk, after performing optical writing, the optical disk is taken out from the optical disk recording apparatus as a completely different work, and the optical disk is set in the printer again. Since then, it has been necessary to perform a very complicated and time-consuming work such as newly inputting information necessary for printing using a personal computer or the like.
[0003]
For example, as in the case of (Patent Document 1), a standard bay type personal computer is conventionally known as a printer shape. However, the printer described in (Patent Document 1) is independent of the optical writing mechanism, and when performing label printing, it is necessary to take out the disc and reload it into the printer.

[0057]
FIG. 10 is a diagram showing a marking sensor output at the time of searching for a printable area, and FIG. 11 is a diagram showing an output of the pickup unit at the time of searching for a printable area. FIG. 12 shows a bitmap image of the scanned optical disk.
[0058]
In FIG. 10, when the marking sensor 101 reads the marking print area while rotating the optical disc 203, the marking sensor 101 outputs 0 in the marking print area (blank area) where nothing is recorded, and the recorded marking print In the area (printed area), the marking sensor 101 outputs 1. Thus, the system control unit 107 can identify the blank area and the printed area by detecting the output of the marking sensor 101.
[0059]
In FIG. 11, when data is recorded on the optical disc 203 for the first time, data indicating a count start bit, for example, “11” is recorded at an arbitrary position on the outermost periphery, and all the rest are “101010. Record the data “・”. By counting the number of data “1” read by the pickup unit 117 from the start bit to the output “1” of the marking sensor 101 (T 1) and storing it in the memory 106, it is possible to accurately start the printed region. To figure out.
[0060]
Similarly, the end position of the printed area is grasped by counting and storing the data “1” during T2.

[0062]
In FIG. 12, the system control unit 107 prints a bitmap image area (shaded area in FIG. 12) corresponding to a partial annular area from the marking 301 printed on the outermost periphery of the optical disk 203 to the vicinity of the center of the optical disk 203. The area of the bitmap image corresponding to the other area in the label is regarded as a newly printable area.
[0063]
FIG. 13 shows an example of a menu screen at the time of label printing, which realizes a simple operation only by selecting a desired print item.
[0064]
In FIG. 13, on the menu screen, for example, the title of the recorded content, the name of the performer, etc. are displayed from the data captured in advance before recording. In addition, a menu for specifying a division method at the time of label printing and a menu for selecting whether to print an image on the label are also displayed. A check box is displayed on the left side of these menus. The user can check the check box to determine whether or not to print the title, the name of the performer, etc. on the label surface, in what number of areas the entire label surface is printed, and part of the image data ( For example, it is possible to select whether or not to print an image of a scene that remains impressive in a movie.
[0065]
FIG. 14 is a flowchart showing a series of operations from optical writing to label printing processing according to the embodiment of the present invention.
[0066]
In the following, a case where a movie is additionally recorded on a label-printed DVD-RAM in which one title has already been recorded in a partial area of the label will be described as an example.
[0067]
The user selects and determines the desired recording content through a distribution service such as TV reception or the Internet. At this time, accompanying data, that is, information such as a title and a performer name is stored in a memory 106 provided in the system control unit shown in FIG. When the user presses the eject switch 102, the system control unit 107 issues a command to the mechanical control unit 111, and the mechanical control unit 111 causes a current to flow to the tray motor 113 through the motor control unit 108. As a result, the screw shaft 201 rotates, the disk tray 202 slides and is ejected, and the optical disk 203 can be set.
[0068]
When the eject switch 102 is pressed again after setting the optical disc 203, the screw shaft 201 is rotated in the reverse direction by passing an electric current through the tray motor 113 in the opposite direction, and the disc tray 202 is stored. . The state at this time is shown in FIG.
[0069]
Thereafter, the spindle motor 114 is rotated, and the mechanical control unit 111 controls the thread motor 115 and the pick actuator 116 (not shown), and the optical disc 203 is irradiated with laser light to write the selected recording contents in a prescribed place. .
[0070]
After the writing is completed, the carriage motor 112 is rotated to move the carriage 204 to the center via the carriage belt 502, the spindle motor 114 is rotated as indicated by reference numeral 8a in FIG. 9, and the spindle motor 114 is rotated at a low speed. In this state, the marking 301 at the outermost periphery of the label surface is scanned by the marking sensor 101 attached to the lower surface of the carriage 204 shown in FIG. The output of the marking sensor 101 at this time is as shown in FIG. 10, and 0 is output in the blank area and 1 is output in the printed area.
[0071]
At the same time as the marking 301 is scanned, the data on the outermost periphery in the optically recorded area on the lower surface of the optical disc 203 is read by the pickup unit 117. An output signal when the pickup unit 117 reads the optical data is as shown in FIG.
[0072]
The output of the marking sensor 101 and the output of the pickup unit 117 are sent to the system control unit 107, respectively. The system control unit 107 uses the output (optical data) of the pickup unit 117 as position data in the rotation direction of the optical disc 203, and ascertains the exact position of the printed area of the optical disc 203 by associating the two, and displays it on the memory 106. A bitmap image as shown in FIG.
[0073]
After the bitmap image is created, the rotation of the spindle motor 114 is stopped. Here, the spindle motor 114 uses a general three-phase motor for optical disc equipment. Therefore, the drive current distribution to each phase at the time of stopping rotation is maintained, or a current is passed through only one phase. Thereby, the optical disk 203 is held so as not to rotate due to vibration or the like during label printing.
[0074]
Note that the current that flows to the spindle motor 114 at this time is desirably a minimum current value that allows the optical disc 203 to be reliably held in consideration of heat generation of the spindle motor 114. However, the present invention is not limited to this.
[0075]
Further, as shown in FIG. 4, the present apparatus has the optical disc 203 in the center of the optical disc 203 as viewed from the front of the device when the disc tray 202 of the optical disc 203 is completely stored in the device body (the position of the tray in the optical read / write state). When moved, the positional relationship is such that the marking sensor 101 is positioned on the marking 301 located on the outermost periphery of the optical disc 203.
[0076]
Next, application software (not shown) installed in the personal computer 103 is activated. This application software displays a menu prepared in advance as shown in FIG. On this menu, a pre-captured title, name of performer, print contents such as a certain scene, print location, size, and the like are displayed. Therefore, the user can create a desired label design with a simple operation of only selection.
[0077]
The user displays a preview of the selected content on the display 104, and if it is NG, the print content is changed again. If OK, the user inputs an instruction to the effect that the print content has been confirmed. When the print contents are determined, the system control unit 107 sends print data and a control signal to the mechanical control unit 111 according to the bitmap data created on the memory 106. The mechanical control unit 111 controls the reciprocating motion of the carriage 204 via the motor control unit 108 and the carriage motor 112, and controls the moving operation of the disk tray 202 by the tray motor 113. The discharge control unit 110 controls the carriage 204 and the disk. In synchronization with the movement of the tray 202, the discharge timing and discharge amount of each nozzle (not shown) of the print head 118 are controlled, and label printing is performed on the selected area. At this time, marking is performed with yellow ink on the outermost periphery of the area where label printing is performed for recognition at the next label printing.
[0078]
In this embodiment, for simplicity of explanation, a stepping motor is used as the carriage motor 112 and an open loop system is used for carriage position management. With the configuration using the motor and the encoder sensor, the position management with feedback can be performed to further improve the printing quality. Similarly, in the sliding operation of the disc tray 202, a stepping motor is used in this system, but higher quality printing can be performed using a DC motor and an encoder sensor.
[0079]
【The invention's effect】
As described above, according to the present invention, after the optical recording of the optical disc is completed, a new printer is prepared for label printing and the optical disc is set again. It is possible to complete a series of operations from a single device, from recording video and music to label printing, quickly and easily, without having to perform complicated operations such as inputting new information such as new scenes. Become.
[0080]
In addition, the function of marking on the label of the optical disc and detecting it to determine the printable area enables multiple label printing on a single optical disc, which was impossible before, and increases the capacity of the media. It becomes possible to facilitate the management and retrieval of the recorded contents against the increase in the recorded contents on one optical disk.
