Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information processing apparatus capable of recording and / or reproducing a plurality of types of discs, and more particularly, to an information processing apparatus that shortens a processing time for disc determination.
[0002]
[Prior art]
2. Description of the Related Art A conventional information processing apparatus capable of recording and / or reproducing a plurality of types of discs includes a determination unit for automatically determining a loaded disc.
[0003]
FIG. 6 shows a flow of a disk determination process by a conventional determination unit.
That is, when a disk is loaded into the apparatus main body, the determining means first determines whether the loaded disk is a CD (step S41). As a result, when the loaded disk is a CD (when determined to be Yes in step S41), information that a CD is loaded is stored in the drive (step S42), and a command wait state is set. (Step S45).
[0004]
On the other hand, if the result of the determination is that the loaded disk is not a CD (if No is determined in step S41), it is next determined whether or not the loaded disk is a DVD (step S43). As a result, if the loaded disc is a DVD (if Yes is determined in step S43), information that a DVD is loaded is stored on the drive side (step S44), and a command wait state is set. (Step S45).
[0005]
On the other hand, as a result of the determination, if the loaded disk is not a DVD (if No is determined in step S43), error determination is made that the disk determination is impossible (step S46).
[0006]
As described above, in the conventional disc determination process, discs are determined in a predetermined order. Therefore, when the loaded disk is a DVD, the determination process in step S41 is a wasteful time, and there is a problem that a considerable waiting time is required until the DVD is reproduced. The same applies to the case where a CD is loaded when the flow of the determination processing is the determination of DVD first and then the determination of CD. As described above, in the conventional disk determination processing, there is a problem that the disk determination order is determined in advance.
[0007]
On the other hand, as one method for solving such a problem, two sets of a CD pickup unit and a signal processing circuit for CD and a DVD pickup unit and a signal processing circuit for DVD are mounted, and a signal processing circuit for CD and a signal for DVD are mounted. There has been proposed an optical pickup device having a configuration in which a circuit switching switch for switching between a processing circuit and a processing circuit is provided at a corner of a disk mounting surface of a drawer (tray) (for example, see Patent Document 1).
[0008]
According to this optical pickup device, when a CD is placed on the drawer, the circuit is switched to the CD side with the drawer pulled out from the device main body, thereby shifting to the CD reproduction mode, and storing the DVD in the drawer. When loading, the circuit switch is switched to the DVD side with the drawer pulled out from the main body of the apparatus, so that the mode shifts to the DVD playback mode. Therefore, the disc determination processing is omitted and the subsequent playback operation is performed quickly. Is possible.
[0009]
[Patent Document 1]
JP-A-10-91992
[Problems to be solved by the invention]
However, in the device disclosed in Patent Document 1, it is necessary to mount two sets of signal processing systems, a CD pickup unit and a signal processing circuit for CD, and a DVD pickup unit and a signal processing circuit for DVD. At the same time, there is a problem that the cost is high.
[0011]
Also, for example, if a circuit switch is erroneously switched to the DVD side and a drawer is loaded in the main body of the apparatus even though a CD is loaded, it is impossible to play back as it is. The user has to pull out the drawer again from the apparatus main body and switch the circuit switching switch to the CD side, which requires a cumbersome operation.
[0012]
The present invention has been devised to solve such a problem. The purpose of the present invention is to reduce the disc determination time by instructing the type of disc to be loaded by the user, and to reduce the discrimination time by the user. It is an object of the present invention to provide an information processing apparatus capable of automatically performing disc discrimination and starting a reproducing operation or a recording operation even when the type is different.
[0013]
[Means for Solving the Problems]
An information processing apparatus according to the present invention is provided in an information processing apparatus capable of recording and / or reproducing a plurality of types of disks, a determination unit for automatically determining a type of a loaded disk, and an operation panel unit of an apparatus main body. Instruction means for instructing the type of disc to be loaded by a user, wherein the judgment means performs disc judgment with priority given to the instruction by the instruction means, and if different from the instruction, performs automatic judgment as before. Features.
[0014]
In this case, the instructing means may be a changeover switch capable of switching to one of three types of modes: a CD priority mode, a DVD priority mode, and an automatic determination mode.
[0015]
In addition, as the instructing means, it is also possible to use an eject switch for performing an operation of pulling a disk placed on the tray into the apparatus main body and an operation of pulling out the disk from the apparatus main body. The mode is switched to one of three types of modes, a CD priority mode, a DVD priority mode, and an automatic determination mode, depending on how the eject switch is pressed.
[0016]
More specifically, the mode is switched to one of three types of modes, a CD priority mode, a DVD priority mode, and an automatic determination mode, depending on the number of times the eject switch is continuously pressed at the time of the pull-in operation or the pull-out operation of the disk. For example, when the eject switch is pressed once, an automatic determination mode is input, when the switch is continuously pressed twice, a CD priority mode is input, and when the eject switch is pressed continuously three times, an instruction signal indicating a DVD priority mode is input to the determination means. In accordance with this instruction signal, disc determination is preferentially performed in the mode instructed. If the result of the determination is different from the specified one, the automatic determination is performed as before. Thus, even if the user instructs the type of the loaded disk by mistake, the automatic determination mode is finally executed, so that the loaded disk can be reliably determined.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
[Embodiment 1]
FIG. 1 shows an example of the information processing apparatus of the present invention. The information processing apparatus of the present invention may be a reproduction-only type or a recording / reproducing type, but the first embodiment exemplifies a system configuration of a recording / reproducing type information processing apparatus.

The servo processing circuit 9 is bidirectionally connected to a system controller 10 that controls the entire apparatus.
[0020]
A DRAM 6 serving as a buffer for temporarily storing data actually read from the optical disc 1 is bidirectionally connected to the digital signal processing circuit 7, and a system controller 10 has parameters for the disc and laser power. An EEPROM 11 for storing unique information such as parameters is bidirectionally connected. Further, the system controller 10 is connected to a key input unit 13 for inputting operation signals of various function switches such as an eject switch, a volume switch, and a changeover switch which is a feature of the first embodiment to the system controller 10. Have been.
[0021]
Further, the system controller 10 and the digital signal processing circuit 7 are configured such that an interface controller (I / F controller) 12 for connecting to a host computer or the like (not shown) is bidirectionally connected. Although not shown, the system controller 10 stores a determination processing program for executing a disk determination process, which is a feature of the present invention, in an internal memory (ROM or the like).
[0022]
FIG. 2 shows an external view of the information processing apparatus having the above configuration.
An operation panel section 22 on the front of the apparatus main body 21 is provided with a drawer 24 for a tray 23. A volume switch 25 is provided on the left side of the lower portion of the outlet 24 to be pulled out, and a changeover switch 26 and an eject switch 27 are provided on the right side.
[0023]
FIG. 3 is an explanatory diagram in which the changeover switch 26 is enlarged.
The changeover switch 26 can be switched to one of three types of modes: a CD priority mode, a DVD priority mode, and an automatic determination mode. FIG. 6A shows a state in which the changeover switch 26 is switched to the automatic determination mode. In this automatic determination mode, the CD or DVD of the CD or DVD is automatically determined based on the light reflectance and the like as in the conventional processing. Perform type determination. FIG. 4B shows a state in which the changeover switch 26 has been switched to the CD priority mode. In this CD priority mode, the automatic judgment processing which has been performed so far is skipped and a CD is inserted. To execute the processing of the CD. FIG. 3C shows a state in which the changeover switch 26 has been switched to the DVD priority mode. In this DVD priority mode, the automatic determination process which has been performed so far is skipped and a DVD is inserted. To execute the DVD process. However, if the user sets the CD priority mode shown in FIG. 2B and the DVD priority mode shown in FIG. 2C by mistake, information cannot be read from the disk. The judgment mode is executed.
[0024]
Next, in the information processing apparatus having the above configuration, a disc determination process when a user loads the optical disc 1 into the apparatus main body will be described with reference to a flowchart shown in FIG.
[0025]
Before placing the optical disc 1 on the tray 23 pulled out from the apparatus main body 21 and loading the optical disc 1 into the apparatus main body 1, the user switches the changeover switch 26 to indicate the type of the loaded optical disc 1 (step S1). The system controller 10 determines the type of the loaded optical disc 1 based on the instruction signal (Step S2).
[0026]
As a result, when the changeover switch 26 is at the position of the CD priority mode and the instruction signal indicates the CD priority mode, the automatic determination processing which has been performed so far is skipped, and information indicating that a CD is inserted is internally stored. (Step S3). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S4). If it is determined that the reading or writing is possible, the processing of the CD is executed (step S5), and the apparatus waits for a command. The process proceeds (step S10). On the other hand, when it is determined that reading or writing is impossible, the automatic determination process is performed as before (step S9).
[0027]
On the other hand, as a result of the determination in step S2, when the changeover switch 26 is in the DVD priority mode position and the instruction signal indicates the DVD priority mode, the automatic determination process which has been performed is skipped, and the DVD is inserted. Is stored internally (step S6). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S7). If it is determined that the reading or writing is possible, the DVD is set to a state where the processing of the DVD can be executed (step S8), and a command waiting state is set. The process proceeds (step S10). On the other hand, when it is determined that reading or writing is impossible, the automatic determination process is performed as before (step S9).
[0028]
If the result of the determination in step S2 indicates that the changeover switch 26 is in the position of the automatic determination mode and the instruction signal indicates the automatic determination mode, the automatic determination process is performed as before (step S10).
[0029]
As described above, according to the information processing apparatus of the first embodiment, when the CD priority mode or the DVD priority mode is designated by the changeover switch 26, the reading or the reading is immediately performed without performing the conventional automatic determination mode. Since writing can be performed, the processing time for disc determination can be reduced.
[0030]
[Embodiment 2]
The information processing apparatus according to the second embodiment differs from the information processing apparatus according to the first embodiment in that the changeover switch 26 is deleted from the operation panel unit 22 of the apparatus main body 21 and the eject switch 27 is also used as the changeover switch 26 instead. It is configured.
[0031]
Specifically, at the time of the pull-in operation or the pull-out operation of the tray 23 on which the optical disc 1 is placed, one of three types of modes, a CD priority mode, a DVD priority mode, and an automatic determination mode, depends on the number of times the eject switch 27 is continuously pressed. The mode is specified.
[0032]
For example, an instruction signal for instructing the automatic determination mode when the eject switch is pressed once, the CD priority mode when pressing twice, and the DVD priority mode when pressing continuously three times is output to the system controller 10. Things.
[0033]
Next, in the information processing apparatus having the above configuration, a disc determination process when a user loads the optical disc 1 into the apparatus main body will be described with reference to a flowchart shown in FIG. However, here, a case will be described in which the disk determination process is performed during the disk pull-in operation.
[0034]
The user pushes the eject switch 27 to pull out the tray 23 from the apparatus main body 21. In this case, when the system controller 10 confirms that the operation of the eject switch 27 is a disk pulling-out operation by confirming the position of the tray 23 by a tray detection sensor or the like (not shown), in this case, the disk determination process is performed. Instead, only the operation of pulling out the tray 23 is executed. At this point, when the eject switch 27 is operated next time, the system controller 10 recognizes that the operation is a pull-in operation of the tray 23 and that the mode is a mode for executing the disc determination process. Next, the system controller 10 monitors whether or not the eject switch 27 has been pressed (step S21).
[0035]
Thereafter, when the user places the desired optical disc 1 on the pulled-out tray 23 and operates the eject switch 27 to pull the tray 23 into the apparatus main body 21 (if Yes is determined in step S21), The system controller 10 checks whether the switch operation is a disk pull-in operation (step S22). In this case, since it is a disk pull-in operation, the system controller 10 performs a pull-in operation of the tray 23 into the apparatus main body 1 (step S23), and starts a disk determination processing program at this time to execute the disk determination processing. Is started (step S24).
[0036]
That is, the system controller 10 checks how many times the eject switch 27 has been pressed (steps S25 to S27). As a result, when the eject switch 27 is pressed once (when it is determined Yes in Step S25), the automatic determination process is performed as usual (Step S28), and thereafter, the process shifts to a command waiting state (Step S28). S29).
[0037]
On the other hand, if the eject switch 27 is continuously pressed twice (No in step S25, and Yes in step S26), it is determined that the CD priority mode has been set, and the automatic determination that has been performed so far has been performed. The process is skipped, and information that a CD is inserted is stored internally (step S30). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S31). If it is determined that reading or writing is possible (if Yes is determined), it is set as a state where CD processing can be executed (step S32). ), And shifts to a command waiting state (step S29). On the other hand, when it is determined that reading or writing is not possible (No in step S31), an automatic determination process is performed as before (step S28).
[0038]
On the other hand, if the eject switch 27 is continuously pressed three times (No in step S25, No in step S26, and Yes in step S27), it is determined that the DVD priority mode is set, By skipping the automatic determination process that has been performed, information that a DVD is inserted is stored internally (step S33). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S34). If it is determined that reading or writing is possible (determined as Yes), a state is set in which DVD processing can be executed (step S35). ), And shifts to a command waiting state (step S29). On the other hand, when it is determined that reading or writing is not possible (No in step S34), the automatic determination process is performed as before (step S28).
[0039]
In step S22, if the operation of the eject switch 27 is not a disk pull-in operation, another process (specifically, a disk pull-out operation) corresponding to the switch operation is performed (step S36). In the above-described processing operation, the automatic determination processing in step S28 is also performed when it is determined in step S27 that the eject switch 27 has been pressed three or more times. In this case, error processing is performed. Is also good.
[0040]
As described above, according to the information processing apparatus of the second embodiment, when the CD priority mode or the DVD priority mode is designated by the number of times the eject switch 27 is pressed during the disk pull-in operation, the conventional automatic determination processing is performed. Since reading or writing can be immediately performed without performing the processing, the processing time for disc determination can be reduced.
[0041]
In the second embodiment, the disk determination process based on the number of times the eject switch 27 is pressed is performed during the disk pull-in operation, but may be performed during the disk pull-out operation.
[0042]
In the second embodiment, the automatic determination mode, the CD priority mode, and the DVD priority mode are simply distinguished by the number of times the eject switch 27 is pressed. However, the present invention is not limited to this. For example, a normal one-time press may be set to the automatic determination mode, a long press (for example, for one second or longer) may be set to the CD priority mode, and two long presses may be set to the DVD priority mode. In this case, the number of times the eject switch 27 is pressed when the mode is designated can be reduced. In addition to this, various methods can be devised as to how to press the eject switch 27 for distinguishing each mode, and such mode determination based on how to press the eject switch 27 can be performed by software on the system controller 10 side. It is possible to process it.
[0043]
Further, when a mode is designated by pressing the eject switch 27, a display unit such as an LED is provided on the operation panel unit 22 in order to further clarify which mode is designated. For example, the user may be notified of the designated mode by turning off the light in the automatic determination mode, turning on the light in the CD priority mode, and blinking in the DVD priority mode.
【The invention's effect】
According to the information processing apparatus of the present invention, the operation panel unit of the apparatus main body is provided with an instruction means for instructing the type of the disk to be loaded by the user. , It is possible to reduce the time required for the conventional disk determination process.
