In the prior art, the reproduction condition applied in the initial setup is always fixed to the disc type as the first type of optical disc, so that the tendency of the disc type usage frequency used by the user of the optical disc apparatus is completely reflected. There is a problem that is not done. That is, for example, if the first type optical disc on which the optical disc apparatus first sets up is a CD-R, even if the user of the disc apparatus tends to use the DVD-R frequently, the CD-R is first used. Since the setup is performed under the reproduction condition of −R and this setup is not completed, the setup is attempted under the reproduction conditions of the second type, third type,... Optical disks. For this reason, it takes a long time before the setup is performed under the reproduction condition of the DVD-R that is the actual disk used.

[0014]
Reference numeral 12 denotes a system control unit including a control microcomputer that controls the entire apparatus. The system control unit 12 controls each unit of the apparatus and performs overall management.
[0015]
The standard of the type of the optical disk 9 is detected, for example, by a processing flow as shown in FIG. 4, and the system control means is transmitted from the recording / reproducing means 8 via the recording / reproducing signal processing means 6 or directly. 12 is transmitted.
[0016]
Next, an example of a general processing flow for determining the type of optical disk based on what type of optical disk is mounted in the optical disk device and performing setup will be described with reference to FIG.
[0017]
When the setup is started, the optical head 10 is first moved to the inner peripheral side of the optical disc 9 in step S1. Next, in step S2, various setting values are set for an A-type optical disk, for example, a DVD disk, whatever the type of the optical disk 9 is. The various setting values referred to here are setting values for servo control necessary for optical recording / reproducing described above, such as a focus error gain value. Next, in step S3, the lens of the optical head 10 is lowered by a fixed amount, and in step S4, the laser for the A type optical disk is turned on. Which laser is turned on depends on the type of the optical disc, and the wavelength, output, and the like are different. For example, the wavelength is 630 nm for a DVD disk and 780 nm for a CD disk. It is step S5 that various adjustments are started based on the reflected light from the optical disk 9 and signals such as a focus error signal are measured. If the signal determination in step S6 satisfies a certain condition, the optical head 10 moves to the outer peripheral side of the optical disk 9, and the same measurement and determination as in the case of the inner peripheral are performed in step S7. Step S8. Also in step S8, if certain conditions are satisfied, the optical disk 9 is determined to be an A type optical disk (step S9). After the optical disk 9 is determined to be an A-type optical disk, it is further determined in step S10 which optical disk type is the A-type optical disk (for example, it is determined to be a k-th type optical disk). Various adjustments are made for the k types of optical disks. That is, although not described in detail here, for example, when the type A optical disk is a DVD disk, in the determination and adjustment in step S10, it is determined whether the disk is a single-layer disk or a double-layer disk, or a DVD-RAM, DVD-R, After a type determination such as DVD-RW is performed, a set value for reproducing data recorded on the optical disk is set or adjusted according to the type of the optical disk. In addition, in the adjustment in step S10, when a write test operation is required for a writable optical disk, a write confirmation operation is also performed.
[0018]
On the other hand, if it is determined in step S6 or S8 that the optical disk 9 is not an A type optical disk, the process proceeds to step S11, and various setting values of a B type optical disk, for example, a CD disk, are set. The various set values are set values for servo control necessary for optical recording / reproducing described above, such as a focus error gain value. In step S12, the lens of the optical head 10 is lowered by a certain amount. In step S13, the type B optical disk laser is turned on. It is step S14 that various adjustments are started based on the reflected light from the optical disk 9 and signals such as a focus error signal are measured. If the signal determination in step S15 satisfies certain conditions, the optical disk 9 is determined to be a B-type optical disk (step S16). After the optical disk 9 is determined to be a B-type optical disk, it is further determined in step S17 which optical disk type is the B-type optical disk (for example, it is determined to be an n-th type optical disk). Various adjustments are made for the n types of optical disks. That is, although not described in detail here, for example, when the type B optical disk is a CD disk, after the type determination such as CD-ROM, CD-R, and CD-RW is performed in the determination and adjustment in step S17. In accordance with the type of the optical disk, a set value for reproducing data recorded on the optical disk is set or adjusted. In addition, in the adjustment in step S17, if a write test operation is necessary for a writable optical disk, a write confirmation operation is also performed.
[0019]
If it is determined in step S16 that the optical disk 9 is not a B-type optical disk, the process proceeds to step S18, where it is determined that there is no optical disk 9 or mis-chucking. Although not shown in FIG. 4, in the case of an optical disk apparatus that supports more types of optical disks, in step S18, various setting values of the C type optical disk are set, and when the A type or B type optical disk is determined. In this case, the disc type is determined in the same manner as described above, and the disc type and the E type are further determined.
[0020]
Here, a problem in the processing flow shown in FIG. 4 is that, for example, the type A disk is a DVD disk, the type D disk is a CD disk, and the optical disk 9 mounted on the optical disk device is a CD disk. Is the case. In this case, although the CD disk is mounted on the optical disk device, various settings and adjustments are performed while the disk is regarded as a DVD disk until step S6 or step S8 is passed. It takes time to set / adjust. Further, even if the user of the optical disc apparatus usually uses almost no DVD disc, for example, frequently uses only the CD-ROM disc in the optical disc apparatus, various adjustments and settings for the DVD disc are performed every time. After that, it is necessary to wait for adjustment and setting for the CD and also for the CD-ROM, which takes time. In particular, in a device that handles the writable optical disk 9, since the setup process of the writable disk takes a long time, the above-mentioned problem becomes more remarkable, causing annoyance to the user.
[0021]
The optical disk device of the present invention solves the above problem. FIG. 1 is a block diagram illustrating a schematic configuration of an optical disc device according to an embodiment of the present invention. 1, the same components as those shown in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted to avoid duplication.
[0022]
In FIG. 1, reference numeral 30 denotes a priority processing registration unit for registering and setting the standard of the optical disk to be set up with the highest priority when the optical disk 9 is mounted. The priority information is referred to by the system control unit 12. Here, the standard of the optical disk to be set up with the highest priority may be set by the user or automatically set to the standard of the optical disk used last time. May be set automatically. These three setting modes are selectable by the user, and are set by calling the mode setting screen of the image display means 15 using appropriate input means (not shown). When performing the setting, the highest priority disk type is set on the disk type selection screen.
[0023]
Next, an example of the main part of the processing flow of the present embodiment for determining the type of optical disk based on what kind of optical disk is mounted in the optical disk device and performing setup will be described with reference to FIG. In FIG. 2, the same reference numerals are given to the same processing steps as those in FIG.
[0024]
When the setup is started, the optical head 10 is first moved to the inner peripheral side of the optical disc 9 in step S1. Next, in step S20, it is determined whether or not priority information is registered in the priority processing registration unit 30. If the standard of the optical disk to be set up with the highest priority is registered in the priority processing registration means 30, for example, if the CD-R disk is registered as the highest priority optical disk, in step S21 the CD-R disk , Are set. The various set values are set values for servo control necessary for optical recording / reproducing described above, such as a focus error gain value. Next, in step S22, the lens of the optical head 10 is lowered by a fixed amount, and in step S23, the laser for the optical disk of the highest priority type is turned on. It is step S24 that various adjustments are started based on the reflected light from the optical disk 9 and signals such as a focus error signal are measured. In the subsequent signal determination in step S25, if a certain condition is satisfied, the optical disk 9 is determined to be the highest priority type optical disk (step S26). After the optical disc 9 is determined to be the highest priority type optical disc, various adjustments for the highest priority type optical disc are further performed in step S27. Although not described in detail here, for example, when the highest-priority type optical disk is a CD-R disk, a setting value for reproducing data recorded on the CD-R disk is set or adjusted in the adjustment in step S27. Adjusted.
[0025]
On the other hand, if it is determined in step S20 or S25 that the optical disk 9 is not the optical disk of the highest priority type, the flow shifts to step S2 in FIG. 4, and shifts to the above-described conventional disk type determination / setup processing flow. .
[0026]
Although not shown in FIG. 2, after the disk type is finally determined, the system control unit 12 stores the determined disk type in a suitable storage unit as a previously used disk type, and The number of times of use of the disc type in the use history storage unit (not shown) is counted up by one, and the number of times of use is registered. Then, when the standard of the optical disk set in the priority processing registration unit 30 is a mode in which the standard of the optical disk used last time is set, the system control unit 12 sets the disk type of the previously used disk stored in the storage unit. In the case of the mode in which the most frequently used optical disc is used as a standard, the type of the most frequently used optical disc is set based on the comparison result of the data in the use history storage unit.
[0027]
In the optical disk device of the present embodiment having such a configuration and operation, in the setup start process, the disk type determination is started by determining whether or not the optical disk is of the highest priority type specified in advance, thereby reducing the time required for the setup. It can be shortened.
[0028]
【The invention's effect】
As described above, according to the present invention, in the process of starting the setup of a disk device, first, the disk type determination is performed in accordance with the user's request or the highest priority reflecting the past usage history of the disk type used by the user. By starting from the determination as to whether or not the disc is a kind disc, it is possible to reduce the time required for the setup.
