BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disc device, a disc type discriminating method for an optical disc device, a discriminating program for executing the disc type discriminating method, and a recording medium recording the discriminating program, and more particularly to disc type discs.

The present invention relates to an optical disc device, a disc type discriminating method for the optical disc device, a discriminating program, and a recording medium, which have reduced time.

[0002]

2. Description of the Related Art In recent years, the amount of data handled by users has been increasing, and the opportunities for handling not only images but also moving images have increased. Therefore, various recording media such as optical discs have been developed as recording media capable of recording such a large amount of data. Especially recently, optical discs (hereinafter,
CD) (compact disc), CD-ROM, CD-R, CD-RW, DVD
(Digital Video Disc), DVD-R, DV
Various types such as D-RAM, DVD + RW, DVD-RW, and MMVF have been developed and put into practical use. On the other hand, on the side of optical disc devices that record and reproduce these discs as recording media, various types of discs that can support a plurality of types of discs have been proposed. When a disc is inserted, the disc type can be quickly and accurately determined. The technique to do is required.

Hereinafter, a process of discriminating a disc type in a conventional optical disc device capable of supporting a plurality of types of discs will be described with reference to a flowchart shown in FIG. In the conventional optical disc apparatus, when an optical disc is loaded, first, the disc type is automatically determined in step S1001, and the disc type is set in step S1002. Adjustment of the servo system and acquisition of management information on the disk are performed, and in step S1004,
Step S1002 from the information recorded on the disc
Check that the type of disc set in is correct.

Specifically, for example, in a state in which a laser beam having a wavelength for a specific disc is emitted, an actuator for pointing an objective lens is driven in the optical axis direction to perform a focus search, and the wavelength of the laser beam ( If the numerical aperture) matches the type of the mounted disc, focus pull-in can be performed, and the disc type determination process ends as successful startup (normal end) in step S1005. If the wavelength of the laser light (numerical aperture) does not match the type of the mounted disk, focus pull-in cannot be performed even if focus search is performed, and the process proceeds to step S1006.

Thus, if the disc type set in step S1002 is incorrect, step S1006 is performed.
In step S1006, it is confirmed whether or not all the reproducible disc types have been set and the activation has been attempted. If all the disk types have been set and booting has been carried out, the flow advances to step S1007 to set "No-Disc / Err-Disc" or the like to the disk type, and then the disk type is determined to have failed to boot in step S1008. The determination process ends.

If it is determined in step S1006 that all the disk types have not been set and booting has been performed, the process advances to step S1009 to determine that the disk type has already been determined to be incorrect in the subsequent disk type determination process. The process of setting not to perform is performed, the process returns to step S1001 and the disc type determination process is repeated.

[0007]

However, in the conventional disc type discriminating process in the optical disc device capable of coping with plural types of discs, when the disc type set by the automatic disc type discrimination is incorrect. In addition, it was found that the disc type was erroneously discriminated for the first time in the subsequent servo adjustment and management information acquisition processing, and the processing was restarted from the beginning, and it took time to start the data recording / playback processing. It had a problem that it was costly. Further, when the user actually uses the disc, even if the discs to be reproduced are the same, the disc type is automatically discriminated every time the disc is loaded, which causes a problem that the startup time becomes long.

The present invention has been made in view of the above conventional problems, and discriminating the disc type by performing disc type discriminating processing at startup using disc type information designated by the user.

The recording / reproducing of the disc 100 includes a data processing unit 106 that performs drive control and data processing via the drive control unit 105, and start-up (start-up processing) before starting the data recording / reproducing processing. ing. Note that audio input / output means such as a microphone and a speaker are omitted.

Here, each component of the disc reproducing apparatus of the present embodiment will be described more concretely including the operation explanation. The pickup 102 adjusts its position by the focus, tracking, and sled drive signals from the drive circuit 104, reads information from the disc 100, and converts it into electric signals. Spindle motor 1
01 controls the rotation of the disk 100 based on the spindle drive signal from the drive circuit 104. The slide motor 103 adjusts the position of the pickup 102 by moving the pickup 102 in the radial direction of the disc 100 according to a drive signal from the drive circuit 104.

The drive circuit 104 includes a drive controller 10

Then, the drive control unit 105 controls the drive circuit 104 based on the status from the drive circuit 104.

Further, the input unit 107 which receives an operation instruction from the user has a function of a type specifying means in the claims, and the user specifies the type of the disc 100 mounted through the type specifying means. To do. More specifically, the type specifying means is realized by a toggle switch,
When the user depresses the toggle switch, the disc type to be specified toggles and the content is displayed on the display unit 108. Therefore, the user confirms the display unit 108 and specifies the type of the disc 100. The disc type set in this way becomes the disc type specified by the user or the disc type that should be prioritized when disc type is discriminated.

FIG. 2 shows a transition diagram for explaining how the disc type setting transits when the toggle switch is pressed. In the figure, from states ST1 to ST6,
AUTO, CD, CD-RW, DVD5, DV
D9 and DVD-RAM are allocated, and the state is cyclically changed by pressing the toggle switch. A in state ST1
When set to UTO, the same automatic discrimination processing as in the conventional case is performed. Further, in the state ST2, the CD, in the state ST3, the CD-RW, and in the state ST4, the DVD5.
However, DVD9 in state ST5, DVD in state ST6
RAM is considered to be user-specified, respectively.

The display unit 108 also displays the operating status of the optical disk device, an input prompt message, etc., but when the information read by the disk startup conflicts with the disk type specified by the user or by the automatic discrimination processing, It also functions as a notification means for displaying a message.

Further, the data processing unit 106 is realized by a CPU, a DSP (digital signal processor) or the like, and has a starting means, a judging means, and
It is provided with an automatic discriminating means. It should be noted that each of these means represents a functional unit, and is specifically realized by a program executed on the CPU or DSP.

The first embodiment is a concrete mode of the optical disc device according to claims 1 and 2, and the disc type discriminating method of the optical disc device according to claims 6 and 7.
When the user specifies the type of the mounted disc via the, the activation means of the data processing unit 106 drives and controls the disc 100 by the device setting based on the disc type specified by the user to activate the disc 100.

When the discriminating means of the data processing unit 106 contradicts the disc type specified by the user when the disc is started, the disc discriminating unit of the data processing unit 106 automatically discriminates the disc type. In this case, the activation means of the data processing unit 106 activates the disk with the device setting based on the disk type determined by the automatic determination means, and the determination means of the data processing portion 106 reads the disk by activation. Whether the disc type discriminated by the automatic discriminating means is correct or not is judged based on the information.

Further, when the discriminating means of the data processing unit 106 contradicts the information read by the disc startup with the disc type specified by the user or the disc type discriminated by the automatic discriminating means, the display unit 108 displays the disc type. A message to that effect is displayed to notify the user.

Hereinafter, the disc type discriminating method of the optical disc apparatus of the present embodiment will be described more specifically with reference to the flowcharts of FIGS. Here, FIG. 3, FIG. 4 and FIG. 5 are flow charts for explaining the startup processing in the optical disk device of the present embodiment.

First, referring to FIG. 3, the start-up process of the optical disk device in the fixed mode will be described. Here, the fixed mode is a mode in which only the disc type set by the user is handled. Further, it is assumed that the user has previously specified the disc type through the input unit 107 (toggle switch) when performing the start-up process of FIG.

First, in step S301, since the disc type has already been specified by the user, the disc type is set without automatically discriminating the disc type on the optical disc device side (data processing unit 106). next,
In step S302, the startup process such as servo is performed by the startup means with the device setting based on the disk type (specified by the user) set in step S301. next,
In step S303, based on the information read from the disc 100 by starting the disc, step S303 is performed.
It is confirmed whether or not the disc type (specified by the user) set in 301 is correct.

The user knows the type of the mounted disc, and the disc type specified by the user and the type of the disc 100 actually mounted are usually the same. That is, in step S303, it is confirmed that the disc type (specified by the user) set in step S301 is correct based on the information read from the disc 100 when the disc is started, and step S30 is performed.
4, the start-up is successful, and the start-up process can be terminated as a successful start-up in a shorter time than in the conventional case.

If the disc type specified by the user is different from the disc type actually mounted in step S303 due to the user's misunderstanding or the like, the process proceeds to step S305 and the disc type is changed to "N".
"o-Disc / Disc-Err" and the like are set, and in step S306, the fact that the activation has failed is displayed on the display unit 108 to notify the user, and the activation process is terminated.

Next, with reference to FIGS. 4 and 5, the start-up process of the optical disk device in the priority mode will be described. Here, the priority mode is a mode in which the disc type set by the user is prioritized when disc type is discriminated. In addition, when performing the start-up process of FIG. 4 and FIG.
It is assumed that the user has specified the disc type via the input unit 107 (toggle switch).

First, in step S401, the disc type has already been specified by the user, and this is preferentially set as the disc type. Next, step S40.
In 2, in the device setting based on the disk type set by the user in step S401 (prioritized by the user), the starting means performs the starting process of the servo or the like. Next, step S4
In 03, based on the information read from the disc 100 by the disc startup, it is confirmed whether or not the disc type set in step S401 (preferred by the user) is correct.

Since the user usually knows the type of the loaded disc, the type of the disc set by the user and the type of the actually loaded disc 100 are the same. That is, in step S403, it is confirmed that the disc type set in step S401 (preferred by the user) is correct based on the information read from the disc 100 by the disc startup, and the startup is successful in step S404. As compared with the conventional case, it is possible to end the activation process as a successful activation accurately in a shorter time.

If the disc type that the user preferentially sets in step S403 is different from the disc type actually mounted in step S403 due to the user's misunderstanding or the like, the process proceeds to step S501 in FIG. Similar to the start-up process, a process is performed so that an incorrect disc type is not selected when disc types are discriminated in the future, and the disc type is automatically discriminated in step S502.

Next, in step S503, the disc type determined by the automatic disc type determination is set, and in step S504, the device setting based on the (automatically determined) disc type set in step S503 is performed by the activation means. Performs startup processing for servos, etc. And step S
In 505, the disc 100 is started by the disc startup.
Based on the information read from, it is confirmed whether or not the disc type (automatically determined) set in step S503 is correct.

If it is determined in step S505 that the disc type set by the automatic disc type determination is the same as the type of the actually mounted disc 100, the process proceeds to step S506, and it is determined that the startup is successful. The process ends.

If it is determined in step S505 that the disc type determined by the automatic disc type determination is different from the type of the actually mounted disc 100, the flow advances to step S507 to reproduce already. Check if all possible disk types have been set and booted.

If it is determined in step S507 that all disk types have been set and booting has been performed, the flow advances to step S508 to set the disk type to "No-Disc /
"Disc-Err" and the like are set, and in step S509,
When the activation fails, the display unit 108 displays that fact to notify the user, and the activation process ends. If it is determined in step S507 that all disk types have not been set and started, the process returns to step S501 to continue the process.

As described above, in the optical disc device and the disc type discriminating method of the optical disc device according to the present embodiment, the disc type discriminating process at the time of start-up is performed by using the disc type information designated by the user. The type determination can be performed accurately, the automatic disc type determination process can be omitted, and the startup (start-up process) time before starting the data recording / reproducing process can be shortened.

Further, in the optical disc device and the disc type discriminating method of the optical disc device of the present embodiment, the disc type automatic discriminating process is performed only when the disc type information designated by the user is inconsistent with the information read by the disc startup. Since the automatic discriminating process of the disc type is omitted as much as possible, the disc type can be discriminated more accurately, and the start-up (start-up process) time until the data recording / reproducing process is started can be shortened. it can.

Second Embodiment Next, an optical disc device and a disc type discriminating method of the optical disc device according to a second embodiment of the present invention will be described. The configuration of the optical disk device of this embodiment is similar to that of the first embodiment.
However, a function (priority order setting means) for the user to set a plurality of kinds of loaded disks 100 with priorities is added.

The priority setting means is the data processing unit 1
06, input unit 107, display unit 108 and storage unit 109
It is realized by. That is, the user uses the display unit 108.
Interactively while referring to the display screen of
Prioritize and set the disc type. In addition,
The disc type with priority set by the user is stored in the storage unit 109, for example, in a rewritable nonvolatile memory (EE).
PROM, flash memory, etc.).

With reference to FIGS. 6 and 7, a specific example in which the user sets a plurality of disk types with priorities at the time of disc type determination will be described. 6 and 7 show
FIG. 9 is an explanatory diagram illustrating a transition of a display screen of the display unit 108 according to a user operation in setting a disc type with a priority order.

When setting the disc types with priorities, first, as shown in the screen D601, the left side of the screen displays the current setting state of the disc type that is prioritized when the disc type is determined, and the screen is displayed. On the right side of, candidates that can be set as the disc type are displayed. An input method guidance display (not shown) is also displayed in any area of the display unit 108. Further, when "0. No designation after" is selected and input as a candidate that can be set as the disc type, the disc types after that are automatically discriminated.

When the user selects and inputs the disc type, the screen changes, and the current setting state of the disc type that is prioritized when the disc type is determined is updated. In this specific example, when "3.DVD5" is selected and input on the screen D601, "DVD5" selected as the setting state is displayed as the priority "1" as shown in the screen D602, and the candidate display on the left side of the screen is displayed. Then, the display of "3.DVD5" is changed as an unselectable candidate.

Similarly, on screen D602, "4.
"DVD9" is displayed on screen D603 as "5. DVD-R.
When "AM", "1.CD" on the screen D604 and "2.CD-RW" on the screen D605 are sequentially selected, the screen display changes, and the disc type to be prioritized when disc type is determined. Has been set with priority.

The disk type discriminating method of the optical disc apparatus of this embodiment in which a plurality of disc types set by the user are prioritized in disc type discriminating will be described more specifically below with reference to the flowcharts of FIGS. 8 and 9. explain. Here, FIG. 8 and FIG. 9 are flow charts for explaining the startup processing in the optical disc apparatus of the present embodiment.

First, in step S801, the internal counter n is initialized to "1". Where the internal counter n
Is a software counter of a program executed by the data processing unit 106, for example.

Next, in step S802, the disk type having the n-th priority among the disk types set by the user is set, and in step S803, step S803 is performed.
In the device setting based on the disc type set in 802,
The start-up means performs a start-up process for the servo and the like. After that, in step S804, the disk 10 is activated by the disk activation.
Based on the information read from 0, it is confirmed whether or not the disk type having the n-th priority set in step S802 is correct.

Since the user usually knows the type of the loaded disc, the type of the disc that the user preferentially sets is the same as the type of the actually loaded disc 100. That is, in step S804, based on the information read from the disk 100 by the disk startup, it is confirmed that the disk type having the nth priority set in step S802 is correct, and the startup is successful in step S805. As compared with the conventional case, it is possible to end the activation process as a successful activation accurately in a shorter time.

If it is determined in step S804 that the disc type having the n-th priority set by the user is different from the disc type actually mounted,
In step S806, 1 is added to the internal counter n. Next, in step S807, it is determined whether or not the internal counter n has exceeded the number of types set by the user as the type of disk to be prioritized at the time of disc type determination. If not, the process returns to step S802.

If it is determined in step S807 that the internal counter n exceeds the number of types set by the user as the type of disc to be prioritized in disc type determination, the process proceeds to step S907 in FIG. Check if it could not be started with.

If it is determined in step S907 that the disc cannot be started in all reproducible disc types, the flow advances to step S908 to set the disc type to "No-Disc".
/ Disc-Err "is set, and step S909 is performed.
Then, the fact that the activation has failed is displayed on the display unit 108 to notify the user, and the activation process ends.

If it is determined in step S907 that the start failure has not been confirmed for all the reproducible disc types, the process proceeds to step S901, and the disc type that is in error is not selected at the time of discriminating the disc type in the future. Thus, the disc type is automatically discriminated in step S902.

Next, in step S903, the disc type determined by the automatic disc type discrimination is set, and in step S904, the device setting based on the disc type (automatically discriminated) set in step S903 is set by the activation means. Performs startup processing for servos, etc. And step S
In 905, the disc 100 is started by the disc startup.
Based on the information read from, it is confirmed whether or not the disc type (automatically determined) set in step S903 is correct.

If it is determined in step S905 that the disc type determined by the automatic disc type discrimination is the same as the type of the actually mounted disc 100, the process proceeds to step S906, and it is determined that the activation is successful. The process ends.

If it is determined in step S905 that the disc type determined by the automatic disc type determination is different from the type of the disc 100 actually mounted, all reproducible discs in step S907 are reproduced. Then, the process returns to the process of setting whether the disk type is set and starting.

As described above, in the optical disc device and the disc type discriminating method of the optical disc device according to the present embodiment, the disc types having higher priorities are sequentially specified from the disc types designated in advance by the user, and By performing the disc type determination process at startup using the identified disc type, the disc type can be accurately determined and the automatic disc type determination process can be simplified. It is possible to shorten the startup (startup processing) time until the start of.

Further, when the disk types having higher priorities are sequentially specified from the disk types designated in advance by the user and the specified disk type information conflicts with the information read by the disk startup, Only the disc type is automatically discriminated, so the disc type is automatically discriminated as much as possible, the disc type is judged more accurately, and the data recording / reproducing process is started up (started up). The processing time can be shortened.
