Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display method, an optical disk device, a display control program and a recording medium, and more specifically, recording information on an optical disk such as a CD-R (writable CD). A display method used in an optical disk device, an optical disk device suitable for implementing the display method, and a display control program for causing a computer for controlling the optical disk device to execute the display method,
And a recording medium on which the display control program is recorded.

[0002]

2. Description of the Related Art For example, a CD having a spiral recording area is produced by using a laser beam output from an optical pickup.
An optical disk device that records and reproduces information on an optical disk such as a (Compact Disc) has been put into practical use.

In recent years, personal computers (hereinafter,
"Personal computer"), as its function improves,
It has become possible to handle AV (Audio-Visual) information such as music and video. Since the amount of such AV information is very large, an optical disk has come to be noticed as a recording medium for the information, and the price of the optical disk has come down, and the optical disk device has become popular as one of the peripheral devices of a personal computer. .

Generally, a CD reproducing device for audio displays a recorded content (song name, playing time, etc.) of a CD (audio CD) and monitors a reproducing situation such as a liquid crystal panel and a fluorescent display tube. Is located on the front of the device. The display color is colorful, and dynamic display such as blinking and scrolling is used together to improve operability and aesthetics. This is because the audio CD reproducing apparatus is used by itself, and the superiority or inferiority of the design including the display content and the display method greatly affects the sales result.

On the other hand, an optical disk device, which is a peripheral device of a personal computer, is not used as a single device, but data from the personal computer is recorded on the optical disc or recorded on the optical disc according to the instruction of the personal computer which is a higher-level device. The data is reproduced and output to the personal computer. And
Usually, one or two LEDs or the like are arranged on the front surface of the optical disc device as a means for displaying information to the user. Whether the optical disc device is being accessed or not The LED is turned on / off according to whether or not it is inserted into the disk, or whether recording or reproduction is in progress. This is because the operation for the optical disk device is only the loading / unloading of the optical disk, and some information is displayed on the display of the personal computer. In addition, it is also one of the reasons that the display means of the optical disk device is inferior to the audio CD reproducing device because the peripheral devices are required to be downsized and low cost.

Therefore, a technique for increasing the information to be notified to the user while suppressing the cost in the optical disk device is disclosed in, for example, Japanese Patent Laid-Open Nos. 6-309857 and 9-
It is disclosed in Japanese Patent No. 35460, Japanese Patent Laid-Open No. 2000-76839, and the like.

Japanese Unexamined Patent Publication No. 6-309857 discloses a disk drive device which uses three or more LEDs to notify whether recording or reproducing and whether the amount of data is large or small. There is. Japanese Unexamined Patent Publication No. 9-35460 discloses an optical disk device that lights an access lamp with a brightness according to a volume volume of headphone output. Japanese Unexamined Patent Publication No. 2000-76839 discloses a disk drive device that uses two or more LEDs and notifies the diagnosis result of the device by the number of times each LED blinks.

Recording systems for recording information on an optical disc are roughly classified into two types. One is a CLV (Constant Linear Velocit) in which the moving speed (linear speed) of the recording area on the optical disc with respect to the optical pickup is constant.
y) method, and the other is CAV in which the number of revolutions of the optical disc (hereinafter referred to as “disc revolution”) is constant.
(Constant Angular Velocity) method.

In the CAV method, since the disc rotation speed is constant, the rotation control of the optical disc at the time of recording is simplified, but the recording density at the outer peripheral portion is smaller than that at the inner peripheral portion of the optical disc, and the entire optical disc is stored. There is a drawback that the capacity cannot be increased.

Therefore, in the so-called CD family of optical disks such as CD-R, the CLV system is mainly used.

In the CLV method, in order to keep the linear velocity constant, the disk rotation speed at the inner peripheral portion and the disk rotation speed at the outer peripheral portion of the optical disk differ greatly. That is, the disk rotation speed at the inner peripheral portion is higher than the disk rotation speed at the outer peripheral portion. Therefore, if the linear velocity is increased in order to shorten the recording time, the number of disk rotations at the time of recording on the inner peripheral portion becomes too large, which may cause a recording error. In addition, the high speed rotation causes an inconvenience that power consumption of the spindle motor and the motor driver increases.

Therefore, the recording area of the optical disk is divided into a plurality of areas (zones) such as an inner circumference, a middle circumference and an outer circumference,
A method that keeps the linear velocity constant in each zone, so-called ZCL
The V method was devised and is disclosed in, for example, Japanese Patent Laid-Open No. 11-66726.

Japanese Unexamined Patent Publication No. 11-66726 discloses an optical disk device for recording data on an optical disk (DVD-RAM) consisting of a plurality of zones by rotating the optical disk at a different rotation speed for each zone. Has been done.

[0014]

Normally, when recording information on an optical disk, the user specifies the recording speed on the personal computer side, and the recording time is displayed on the display of the personal computer according to the recording speed. However, when the recording is performed by the ZCLV method, the optimum recording speed is determined for each zone on the optical disc device side, and therefore the recording speed is not always the recording speed specified by the user depending on the recording position. There is. However, in the conventional optical disk device, the actual recording speed is not displayed in real time as in the above-mentioned publicly known examples, and therefore the user cannot know the actual recording time. There was an inconvenience that the time may be different from the time displayed on the display of the personal computer.

Further, for example, when recording on an optical disc by disc-at-once, the data amount is usually large,
Since the recording time is long, the user is often away from the personal computer, and in some cases, the display is not displayed in order to save power. In such a case, there is an inconvenience that the user cannot confirm whether or not the recording on the optical disc is normally performed.

Further, when reproducing an audio CD, the signal level of the reproduced signal can be displayed on the display of the personal computer depending on the software, but one audio CD usually records about 50 minutes of data. Therefore, the user often listens to music at a place away from the personal computer, and sometimes the display is not displayed for the same reason as above. In such a case, there is an inconvenience that the user cannot grasp the signal level. The signal level has a large image-like element, but for users who are particular about sound quality, the signal level is one of the information necessary for adjusting the amplifier.

As described above, in the optical disk device, it is convenient for the user if the current operating state of the device and other internal information can be accurately displayed on the device itself according to the usage condition. However, in the conventional optical disk device,
Since the internal information is displayed by turning on or off one or two LEDs or the like, only rough information can be displayed.

The present invention has been made under the above circumstances, and a first object thereof is a display that enables the optical disk device itself to accurately display the current internal information according to the usage status. To provide a method.

A second object of the present invention is to provide an optical disk device capable of accurately displaying the current internal information in real time at low cost according to the usage status.

A third object of the present invention is to be executed by a computer for controlling an optical disk device, and it is possible to accurately display the current internal information to the outside in real time according to the usage status of the optical disk device. It is to provide a display control program.

A fourth object of the present invention is to provide a recording medium which, when executed by a computer, can display the current internal information accurately in real time according to the usage status of the optical disk device. It is in.

It is loaded into the main memory (not shown) of the CPU 40.

The RAM 41 is composed of a division position (switching position) and a recording speed when recording by the ZCLV method.
So-called zone parameters are stored in the RAM 41.

As an example, when the recording area of the optical disk 15 is divided into a maximum of three areas (zones), the zone parameters are maximum three recording speeds s ₁ , s ₂ and s.
₃ and a maximum of two switching positions T ₁ and T ₂ . The recording speed s ₁ is the recording speed in the first zone (first zone), and the recording speed s ₂ is the second zone (second zone).
The recording speed in the zone), and the recording speed s ₃ is the recording speed in the third zone (third zone). The switching position T ₁ is a switching position from the first zone to the second zone, and the switching position T ₂ is a switching position from the second zone to the third zone.

In the present embodiment, as an example, FIG.
As shown in, the maximum recording area of the optical disk 15 is 3
It is assumed that the zone parameters are divided into one zone, and five types (five modes) of zone parameters are registered in advance and stored in the RAM 41.

In mode 1, since the switching position is not set, recording is performed without dividing the recording area. And
Since the recording speed s ₁ is set to 8 × speed, the entire recording area is recorded at 8 × recording speed. The 8 × velocity means a 8 × linear velocity as a reference linear velocity (1.2 to 1.4 m / sec).

In mode 2, since the switching position T ₁ is set to 5 minutes, the recording area is divided into two zones at the position of 5 minutes. The zone before 5 minutes is the first zone, and the zone after 5 minutes is the second zone. And
Since the recording speed s ₁ is set to 8 × speed and the recording speed s ₂ is set to 12 × speed, recording is performed at 8 × recording speed in the first zone and 12 × recording speed in the second zone.
It should be noted that in the recording area, minutes, seconds, and
ATIP (Absolute Time In Pre-groove) information including time information (absolute time information) indicated by the number of frames is recorded, and the position on the recording area is indicated by minutes, seconds, and the number of frames.

In mode 3, the switching position T ₁ is 10
Minutes, since the switching position T ₂ is set to 30 minutes,
The recording area is divided into three zones. The first to ten minutes is the first zone, the tenth to thirty minutes is the second zone, and the thirty minutes and thereafter is the third zone. And
Since the recording speed s ₁ is set to 12 times speed, the recording speed s ₂ is set to 16 times speed, and the recording speed s ₃ is set to 20 times speed, FIG.
As shown in (B), recording is performed at a recording speed of 12 times in the first zone, recording is performed at a recording speed of 16 times in the second zone, and recording is performed at a recording speed of 20 times in the third zone.

In mode 4, since the switching position is not set, recording is performed without dividing the recording area. And
Since the recording speed s ₁ is set to 16 × speed, the entire recording area is recorded at 16 × speed.

In mode 5, since the switching position T ₁ is set to 15 minutes, the recording area is divided into two zones at the position of 15 minutes. The zone before 15 minutes is the first zone, and the zone after 15 minutes is the second zone.
The recording speed s ₁ is 16 × and the recording speed s ₂ is 20.
Since the speed is set to double speed, recording is performed at a recording speed of 16 times in the first zone, and recording is performed at a recording speed of 20 times in the second zone.

Further, the RAM 41 is shown in FIG.
As shown in FIG. 5A, a first correspondence table showing the correspondence between the types of optical disks and the display colors of the display unit 50, and as an example shown in FIG. 5B, recording speed and display unit. Second showing the correspondence with 50 display colors
The correspondence table of is stored.

Next, the processing operation when recording data on the optical disk 15 using the optical disk device 20 configured as described above will be described. In the present embodiment, as an example, a blank CD-R by the ZCLV method is used.
Shall be recorded.

When the optical disk device 20 is powered on, the CPU 40 checks whether or not the optical disk 15 is inserted in a predetermined position, and if it is judged that the optical disk 15 is not inserted, it blinks the red LED 50a in a predetermined cycle. .

When the optical disk 15 is inserted, the CPU 4
0 is the TOC (Ta
ble Of Contents) information, PMA (Program Memory Are)
a) Optical disc 1 based on information and ATIP information
Determine the 5 types. Note that CD-R and CD-RW can also be distinguished by the intensity of reflected light. That is, while the reflectance of CD-R is 60% or more, C
It is possible to determine whether the optical disc is a CD-R or a CD-RW by utilizing the fact that the reflectance of D-RW is 15 to 25%.

Then, the CPU 40 obtains the display color corresponding to the type of the optical disk 15 based on the first correspondence table. In the present embodiment, the optical disc 15 is a blank CD-R, so the display color of the display unit 50 is magenta. Then, based on the display color, each LED
Drive signal is output. The display state of the display unit 50 is a lighting state.

When a recording request command is received from the host via the interface 38, the CPU 40 shifts to a recording processing routine. Here, the recording process will be described with reference to FIG. The flowchart of FIG.
Corresponds to a series of processing algorithms executed by.

In step 405, the optimum recording mode is selected based on the type of the optical disk 15.
Here, as an example, it is assumed that the mode 2 is selected.

At step 407, the setting contents (zone parameters) of the selected mode are read. Then, it is determined which zone the recording start position belongs to. Here, since recording is performed on a blank CD-R, the recording start position is included in the first zone. Therefore, the initial value 1 is set in the counter i indicating the zone number.

In step 409, the recording speed is set to the recording speed s ₁ in the first zone (that is, 8 times speed),
A control signal for controlling the rotation of the spindle motor 22 is output to the motor driver 27 so that the linear velocity of the recording area with respect to the optical pickup 23 becomes s ₁ .

In step 411, the color corresponding to the recording speed is displayed on the display unit 50 based on the second correspondence table.
To display. Here, since the recording speed is 8 times,
The display color of the display unit 50 is magenta. And
During recording, in order to notify that it is in the access state,
The display state of the display unit 50 is changed to a blinking state.

When data is received from the host during the above processing, the buffer R is sent via the buffer manager 37.
The data is accumulated in AM34. Then, the buffer manager 37 monitors the amount of data accumulated in the buffer RAM 34 and notifies the CPU 40 when it reaches a predetermined amount. C
The PU 40 uses the notification from the buffer manager 37 as a trigger to instruct the encoder 25 to create write data. As a result, the encoder 25 performs error correction code addition, interleave processing, EFM modulation, and the like on the data extracted from the buffer RAM 34 via the buffer manager 37 to create write data.

At step 413, the ATIP decoder 3
Based on the ATIP information from 1, the motor driver 27 is output with a signal instructing the seek operation of the optical pickup 23 so that the optical pickup 23 is located at a predetermined writing start point.

In step 415, it is determined whether or not all the data has been recorded on the optical disc 15. Here, since the data has not been recorded yet, the determination at step 415 is denied, and the routine proceeds to step 417.

In step 417, it is determined whether the recording position matches the switching position T _i (T ₁ = 5 minutes in this case). If the recording position does not match the switching position T _i , the determination here is denied and step 419
Move to.

At step 419, the ATIP decoder 3
Based on the ATIP information from 1, the optical pickup 23
When it is determined that the position of is the writing start point, the encoder 25 is notified. Then, the encoder 25 records the write data on the optical disk 15 via the laser control circuit 24 and the optical pickup 23. The encoder 25 synchronizes with the rotation of the spindle motor 22 based on the synchronization signal from the ATIP decoder 31. Data recording is performed in frame units (1 frame = 588 channel bits), and C
Each channel bit is recorded on the optical disc 15 in synchronization with the write reference clock output from the PU 40.

Hereinafter, step 415 or step 417
Until the affirmative decision is made in step 415 → 417 →
The process of 419 and the determination are repeated.

On the other hand, when the recording position matches the switching position T _i (T ₁ = 5 minutes in this case) in step 417, the determination in step 417 is affirmative, and the process proceeds to step 421.

In step 421, the position of the currently recorded sector and the number of frames recorded in the sector are stored in the RAM.
41, and recording is interrupted.

At step 423, the counter i is incremented (+1).

In step 425, the recording speed is changed to s _i (i = 2 in this case), and a control signal is output to the motor driver 27 so that the linear velocity of the recording area with respect to the optical pickup 24 becomes s _i . In this embodiment, since the recording area is divided into two zones, the next switching position is not set.

At step 427, since the recording speed has been changed, the display color of the display unit 50 is changed to the color corresponding to the recording speed based on the second correspondence table. Here, since the speed is 12 times, the display color of the display unit 50 is changed to yellow.

In step 429, since the recording is continued after the end position of the data recorded previously, the write start position is detected. In the present embodiment, as an example, Japanese Patent Laid-Open No.
One of the detection methods disclosed in JP-A-49990 is used. Here, the write start position detection processing will be described with reference to the flowchart of FIG. 7 and the timing chart of FIG. The flowchart of FIG. 7 corresponds to a series of processing algorithms executed by the CPU 40.

A frame sync clock is used as a frame sync signal, and a subcode sync clock is used as a sector sync signal. Each synchronization signal is CPU40
Is supplied to.

Here, as an example, the frame 25 (Fr
25) will be described immediately after the recording is stopped, the recording speed is changed, and the frame 26 (Fr26) and the subsequent frames are recorded.

In step 501 of FIG. 7, the position of the previously recorded sector and the number of frames recorded in the sector are read from the RAM 41. Here, since the recording is stopped immediately after the previous recording of Fr25, the number of frames recorded in the sector is 26.

In step 503, a seek operation is performed up to the sector position where recording is restarted, based on the read sector position.

At step 505, the ATIP decoder 3
The ATIP information from 1 is referred to, and it is determined whether or not the sector position where recording is restarted is detected. If not detected, the determination here is denied and the process returns to step 503. On the other hand, if it is detected, the determination here is affirmed, and the routine goes to Step 507.

In step 507, as shown in FIG. 8, the number of frame sync clocks up to the frame sync clock of Fr25 is set in the counter j at the falling timing of the subcode sync clock. Here, as shown in FIG. 8, since the frame sync clock first detected after being set in the counter j is the frame sync clock of Fr3, the value set in the counter j is 22.

In step 509 of FIG. 7, the value of the counter j is subtracted (-1) in synchronization with the frame sync clock included in the information from the analog signal processing circuit 28.

At step 511, the value of the counter j is 0.
Or not. If the value of the counter j is not 0, the determination here is denied and the process returns to step 509.
On the other hand, if the value of the counter j is 0, the determination here is affirmative and the process proceeds to step 513.

At step 513, the number of write reference clocks from the frame sync clock of Fr25 to the recording start position, that is, 588 is set in the counter k.

At step 515, the value of the counter k is subtracted (-1) in synchronization with the write reference clock.

At step 517, the value of the counter k is 0.
Or not. If the value of the counter k is not 0, the determination here is denied and the process returns to step 515.
On the other hand, if the value of the counter k is 0, the determination here is affirmative, and the write start position detection processing ends.

When the process for detecting the write start position is completed as described above, the process returns to step 419 in FIG. 5 to restart recording.

On the other hand, in step 415 of FIG. 5, if all the recording data is recorded on the optical disk 15, the determination in step 415 is affirmative, and step 43
Move to 1.

At step 431, the color corresponding to the type of the optical disk 15 is displayed on the display unit 50 based on the first correspondence table. Here, since the optical disc 15 is a recorded CD-R, the display color of the display unit 50 is cyan. Further, the display state of the display unit 50 is changed from the blinking state to the lighting state in order to notify the user that the recording process on the optical disc 15 is completed.

As described above, when the recording process on the optical disk 15 is completed, the CPU 40 notifies the host of the end of the recording process.

Although the zone parameter mode is selected according to the type of the optical disk 15 in step 405, the present invention is not limited to this, and the zone parameter mode may be selected from the disturbance information of the track error signal.
In this case, before starting recording, the optical disc 15 is accessed based on each zone parameter, the track error signal is detected at a plurality of preset positions, and the disturbance of the track error signal does not fall outside the predetermined range. Select the zone parameter mode. The disturbance of the track error signal is constantly monitored during recording, and the zone parameter may be corrected if there is a possibility that the error is outside the predetermined range. The host can instruct which method to select the zone parameter mode in step 405. Further, the zone parameter mode may be selected based on both the type of the optical disc 15 and the disturbance of the track error signal.

Next, the processing operation when reproducing the data recorded on the optical disk 15 by using the above-mentioned optical disk device 20 will be described. Here, it is assumed that an audio CD on which music data is recorded is reproduced. Regarding the display content of the display unit 50 during the reproduction of the music data, three kinds of display modes (display mode 1, display mode 2, display mode 3) are set in advance, and one of them is selected according to an instruction from the host. One display mode is selected. Further, as shown in FIG. 9A as an example, a third correspondence table showing the correspondence between the signal level of the reproduction signal and the display color of the display unit 50, and as an example in FIG. 9B. As described above, the RAM 41 stores the fourth correspondence table showing the correspondence between the frequency of the reproduction signal and the display color of the display unit 50 and the correspondence between the signal level of the reproduction signal and the display brightness of the display unit 50. . In the present embodiment, the frequency of the reproduction signal is, for example, a low frequency (for example, less than 1 kHz) and a medium frequency (for example, 1 kHz or more and 5 kHz).
(Less than Hz) and high frequency (for example, 5 kHz or more), but the present invention is not limited to this.

When the optical disk 15 is inserted, the CPU 4
0 determines the type of the optical disc 15 in the same manner as above. Then, based on the first correspondence table, the display color of the display unit 50 is changed to the color corresponding to the type of the optical disc 15. Here, the optical disc 15 is an audio C
Since it is D, the display color of the display unit 50 is blue.
Then, the display state of the display unit 50 is turned on.

When a reproduction request is received from the host via the interface 38, the CPU 40 shifts to a reproduction processing routine.

The CPU 40 outputs to the motor driver 27 a control signal for controlling the rotation of the spindle motor 22 based on the reproduction speed (in this case, 1 × speed), and the optical pickup 23 is positioned at a predetermined reading start point. A signal instructing the seek operation is output to the motor driver 27.

When the CPU 40 receives the absolute time information included in the ATIP information from the ATIP decoder 31, the CPU 40 checks whether or not it is the reading start point.

The CPU 40, based on the absolute time information,
When it is determined that the position of the optical pickup 23 is the reading start point, the reproduction signal processing circuit 28 is notified. Then, the reproduction signal processing circuit 28 detects the RF signal, and the CD decoder 32 further performs EFM demodulation, error correction, deinterleave processing, and the like.

Since the data recorded on the optical disc 15 is music data, the output signal of the CD decoder 32 is once stored in the buffer RAM 34, and then converted into analog data by the D / A converter 36, and then the audio device. Etc. are output.

The CPU 40 selects a display mode based on an instruction from the host and controls the display unit 50 based on the selected display mode.

When the display mode 1 is selected, the display unit 50 is displayed at a predetermined time interval (for example, 0.5 seconds).
Display colors sequentially from red → blue → green → magenta → yellow →
Repeatedly change cyan → white → red → blue.
The time interval, the order of colors, the type of color used, and the like can be set arbitrarily. Also, the time intervals do not have to be constant.

When the display mode 2 is selected, for example, after rectifying and averaging the reproduction signal output from the D / A converter 36, the A /
It is converted to digital data by the D converter and the signal level of the reproduced signal is obtained. The signal level of the reproduction signal may be obtained using the reproduction signal output from the CD decoder 32. Then, based on the third correspondence table, the display color of the display unit 50 corresponding to the signal level of the obtained reproduction signal is determined and displayed on the display unit 50. Note that two display units may be installed, one for the right channel and one for the left channel.

When the display mode 3 is selected, the reproduction data once stored in the buffer RAM 34 is subjected to the fast Fourier transform, and the frequency and the signal level of the reproduction signal are obtained. Then, based on the fourth correspondence table, the color corresponding to the frequency of the reproduction signal and the brightness corresponding to the signal level are determined and displayed on the display unit 50.

When the reproduction is completed, the CPU 40 changes the display color of the display unit 50 to the color corresponding to the type of the optical disk 15 (blue in this case) based on the first correspondence table, and at the same time, the display unit 50 displays. The display state is turned on.
