DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device suitable for displaying various kinds of information on a reproducing device or the like.

[0002]

2. Description of the Related Art In recent years, CDs (compact discs) and M
2. Description of the Related Art Disk media such as D (mini-disc) have become widespread and are used for recording various data including music. In a mini-disc on which a user can freely record music and the like, not only audio but also additional information such as character information can be recorded. For example, a user can input a disc name or a track name, thereby recording an album title or a song name.

Further, in a medium called a CD text which is currently under development, character information and the like are recorded as text data in a predetermined area on a so-called CD-type disc. For example, the disc title, song title, performer, lyricist, Composers can be recorded.

[0004] In a reproducing apparatus corresponding to these media, a small-sized display device is provided so as to display a song title, a disc title, time information, and the like during reproduction.

[0005]

By the way, as character information, a track name (song name) and a disc name (disc title) are representative display information as described above, but a display device is relatively small. In many cases, the character display area is not so large on the display screen, so that the track name and the disc name are often switched and displayed according to the operation of the user or the reproduction status.

In this case, in order to inform the user whether the currently displayed character is a track name or a disc name, "TRACK" is displayed near the displayed character.
Characters such as "NAME" and "DISC NAME" are displayed. However, these "TRACK NAME"
Auxiliary displays such as "DISC NAME" have to be quite small and never have good visibility. Then, there is a problem that it is difficult for a user to understand at first glance whether the displayed character is a track name or a disc name.

[0007]

In view of the above, the present invention allows a user to easily determine what the displayed contents correspond to, for example, the display of additional information such as a disc name and a track name. The purpose is to be able to recognize.

For this reason, the display device is provided with display means capable of performing color display and control means for controlling the display operation of the display means. The control means, of the various types of display information to be displayed, the first type of a plurality of first type display information whose information content is set to relate to the entire recording medium, and the information content is stored in the recording medium. The plurality of second-type display information set as those relating to the recorded programs is displayed in the second color in the display means.

Preferably, at least a number given to the recording medium and additional information recorded as information corresponding to the entire recording medium on the recording medium are displayed in a first color as first type display information, A number corresponding to each program recorded on the recording medium and additional information recorded as information corresponding to each program recorded on the recording medium are displayed in a second color as second type display information. In addition, display information that is not set as any of the first type of display information and the second type of display information is displayed in the third color.

In other words, the user can easily confirm the contents of various kinds of display information by distinguishing them on the display by colors according to their contents (attributes).

1. FIG. 1 shows a block diagram of a main part of a mini-disc reproducing apparatus provided with the first display device. This mini-disc reproducing apparatus includes a plurality of discs (mini-disc: recordable / reproducible magneto-optical disc or read-only optical disc)
ＤDn are stored and can be selectively reproduced.

Disk D on which audio data is recorded
Is driven to rotate by a spindle motor 2. The optical head 3 irradiates the disk D with laser light during reproduction.

The optical head 3 detects data from reflected light by a magnetic Kerr effect of a magnetic field pit for a magneto-optical disk, and detects data from a reflected light amount changed by an emboss pit for a read-only optical disk. Is detected. Therefore, the optical head 3 is equipped with a laser diode as a laser output unit, an optical system including a polarizing beam splitter and an objective lens, and a detector for detecting reflected light. The objective lens 3a is held by the biaxial mechanism 4 so as to be displaceable in the radial direction of the disk and in the direction of coming into contact with and separating from the disk. Optical head 3
The whole can be moved in the disk radial direction by a sled mechanism 5.

The information detected from the disk D by the optical head 3 by the reproducing operation is supplied to the RF amplifier 7. The RF amplifier 7 performs an arithmetic operation on the supplied information,
A reproduction RF signal, a tracking error signal, a focus error signal, groove information (absolute position information recorded as a pre-groove (wobbling groove) on the magneto-optical disk D) and the like are extracted. The extracted reproduced RF signal is supplied to the decoder section 8. The tracking error signal and the focus error signal are supplied to a servo circuit 9, and the groove information is supplied to an address decoder 10.

The servo circuit 9 performs various servo driving based on the supplied tracking error signal, focus error signal, track jump command and access command from the system controller 11 composed of a microcomputer, rotation speed detection information of the spindle motor 2 and the like. A signal is generated to control the two-axis mechanism 4 and the sled mechanism 5 to perform focus and tracking control, and to control the spindle motor 2 to a constant linear velocity (CLV).

The address decoder 10 decodes the supplied groove information to extract address information and a groove clock. Address information is stored in the system controller 11
And used for various control operations. Playback R
For the F signal, the decoder unit 8 performs EFM demodulation,
Decoding processing such as IRC is performed. At this time, addresses, subcodes, and the like included in the reproduced RF signal are also extracted as data and supplied to the system controller 11.

The audio data (sector data) decoded by the EFM demodulation and CIRC in the decoder unit 8 is
Buffer memory 1 once by memory controller 12
3 is written. The reading of data from the disk D by the optical head 3 and the transfer of reproduced data in the system from the optical head 3 to the buffer memory 13 are 1.41.
It is performed at Mbit / sec and usually intermittently.

The data written in the buffer memory 13 is read out at a timing when the transfer of the reproduction data becomes 0.3 Mbit / sec, and supplied to the decoder unit 14. Then, the signal is subjected to reproduction signal processing such as decoding processing for the audio compression processing in the decoder section 14, converted into an analog signal by the D / A converter 15, supplied from the output terminal 16 to a predetermined amplifier circuit section, and reproduced and output. For example, they are output as L, R analog audio signals.

The disk D reproduced in this manner is stored in the disk changer 21. The disc changer 21 can store a plurality of discs D (D _{1 to} D _n ) and selectively load them on a disc table. Therefore, the disks D _{1 to} D _n are stored as the storage unit 22, and the disk D in the storage unit 22 is selected and loaded (and unloaded) on the disk table (the reproduction position by the optical head 3). A transport mechanism 23 is provided. The disc exchange operation by the disc transport mechanism 23 is controlled by the changer controller 24.

The changer controller 24 is connected to the system controller 11, and the system controller 1
A predetermined disk is selected from the storage section 21 according to the disk exchange information from 1 and transported by the transport mechanism 23,
Perform loading and unloading operations.
Each disk has 1 to n according to the storage position in the storage section 22.
For example, when the user performs the reproducing operation of the disc number 2, the changer controller 24 loads the disc D ₂ stored in the second position in the storing section 22 and reproduces it. Become.

The operation unit 19 is provided with various keys used for user operation. For example, a reproduction key, a stop key, an AMS key, a fast-forward key, a fast-reverse key, and the like are provided, and their operation information is supplied to the system controller 11. Moreover, and disk selection key for selecting the disc to be reproduced for a plurality of discs D ₁ to D _n, the program reproduction to program the reproduction order of the disc, repeat play to repeatedly play the disc or a specific track, a disc or track Operation keys and the like for special reproduction such as shuffle reproduction for selecting and reproducing in a random order are also provided.

The display unit 20 is constituted by, for example, a liquid crystal full dot color display, and executes an operation of displaying an operation state, a disc number, a track number, time information, a disc name, a track name, and the like based on the control of the display controller 17. . The display controller 17 receives various display information from the system controller 11 and performs an operation of displaying the display information on the display unit 20 based on the display mode control from the system controller 11.

In order to display characters on the display unit 20,
Character font 18 storing dot patterns of various characters
When display information (for example, an ASCII code) for character display is supplied from the system controller 11, the display controller 17 controls display on the display unit 20 based on the dot pattern in the character font 18. Do.

The system controller 11 obtains information obtained from the current operation mode, reproduction address, and TOC information described later, that is, the disc number being reproduced, the track number being reproduced, reproduction time information, and character information such as a disc name and a track name. , Recording date and time information are sequentially supplied to the display controller 17 as display information. As a result, the reproduction operation state, the disc number, the track number, the time information, the disc name, the track name, and the like are displayed on the display unit 20 while being updated as necessary.

The contents displayed on the display unit 20 are switched according to the display mode. An operation key (display mode key) for switching the display mode is provided in the operation unit 19, and the user can arbitrarily switch the display mode. In this example, it is assumed that the disc name, the track name, and the recording date and time can be switched and displayed according to the display mode as additional information such as characters. The display mode may be switched according to the operation of the display mode key, or the system controller 11 may automatically switch according to the operation state.

The display section 20 is a full dot color display. As is already known, a full-dot color display corresponds to each pixel (dot) with R,
G, B 3 primary color pixels are prepared, and R / G /
By controlling the light emission ratio of B, an arbitrary color can be displayed for each pixel. Therefore, under the control of the system controller 11, the display unit 20 can display the display content to some extent freely and in any color using the display area.

When a reproducing operation is performed on the disk D, management information recorded on the disk D, that is, P-TOC (premastered TOC), U-TOC
(User TOC) must be read. The system controller 11 responds to the management information by
The address of the area to be reproduced is determined. This management information is held in the buffer memory 13.
Therefore, in the buffer memory 13, a buffer area for the reproduction data as described above and an area for holding these management information are divided and set. Then, the system controller 11 reads out the management information by executing the reproduction operation on the innermost peripheral side of the disk on which the management information is recorded when the disk D is loaded, and stores the information in the buffer memory 13. Thereafter, it can be referred to at the time of the reproducing operation for the disc D.

Since it is a changer type,
For example, the discs D1 to Dn stored in a period in which reproduction is not performed may be sequentially loaded, and necessary TOC information may be read from each disc D. In this case, in order to prevent data loss even when the power is turned off, it is preferable to provide a non-volatile RAM, an S-RAM having a power backup configuration, and hold the TOC data of each disk. It is.

2. U-TOC Sector Here, the U-TOC sector will be described as management information for managing the reproduction operation of a track (music or the like) on the disk D. In addition, U-
The TOC and the P-TOC are provided.
C is formed in the innermost pit area of the disk 1 and is read-only information. The P-TOC manages the position of a recordable area (recordable user area), a lead-out area, a U-TOC area, and the like on the disc. In the mini disc system, a read-only optical disc (pre-mastered disc) in which all data is recorded in pit form
Can be used, but for premastered discs, P
The music recorded in the ROM by the -TOC can also be managed, and the U-TOC is not formed. A detailed description of the P-TOC is omitted, and here, the U-
-TOC will be described.

FIG. 8 shows the format of U-TOC sector 0. In addition, as the U-TOC sector, sector 0 to sector 7 can be provided,
Sectors 1 and 4 are character information, and sector 2 is an area for recording the recording date and time.

The U-TOC sector 0 is a data area in which management information on a song (track) recorded by the user and a free area in which a new song can be recorded is mainly recorded. For example, the system controller 11
Discriminates an area in which a track to be reproduced is recorded from the U-TOC sector 0 during reproduction, accesses the area, and performs a reproducing operation.

The data area (4 bytes × 588, 2352 bytes) of the U-TOC sector 0 has all 0s at the head position.
Alternatively, a synchronization pattern in which all 1-byte data are formed side by side is recorded. Then the cluster address (Clust
er H) (Cluster L) and an address to be a sector address (Sector) and mode information (MODE) are added by 4 bytes,
This is the header.

A sector is a data unit of 2352 bytes, and 36 sectors constitute one cluster. Regarding the synchronization pattern and address, this U-TOC sector 0
Not only that, but also a P-TOC sector and a data sector in which audio data is actually recorded are recorded on a sector basis. Next, the manufacturer code, model code, and track number (F
irst TNO), track number of last track (Last T
NO), data such as sector usage (Used sectors), disk serial number, and disk ID are recorded.

Further, in order to identify an area of a track (music or the like) or a free area recorded by the user by making it correspond to a management table section to be described later, various tables are used as a correspondence table instruction data section. Pointers (P-DFA, P-EMPTY, P-FRA, P-TNO1 to P-TN
O255) is recorded.

The table pointers (P-DFA to P-TNO25)
5) (01h)
There are provided 255 parts tables from (FFh) to (FFh). In each of the parts tables, a start address serving as a starting point, an end address serving as an end, and mode information (track mode) of the part are recorded. ing. In addition, since the parts indicated in each part table may be successively connected to other parts, link information indicating the part table in which the start address and the end address of the connected parts are recorded can be recorded. Have been. In the present specification, the numerical value with “h” is in a so-called hexadecimal notation. Further, a part refers to a track portion in which temporally continuous data is physically continuously recorded in one track.

In this type of recording / reproducing apparatus, even if data of one music piece is physically discontinuous, that is, even if it is recorded over a plurality of parts, it is reproduced while accessing between parts, so that the reproducing operation is hindered. Therefore, the music or the like recorded by the user may be recorded in a plurality of parts for the purpose of efficient use of the recordable area.

For this reason, link information is provided, and the part tables can be connected by specifying the part tables to be connected, for example, by the numbers (01h) to (FFh) given to the respective part tables.
That is, in the management table section in the U-TOC sector 0, one part table represents one part. For example, for a track configured by connecting three parts, three parts connected by link information are used. The position of the part is managed by the table.

The parts tables from (01h) to (FFh) in the management table section of the U-TOC sector 0 are table pointers (P-DFA, P-EMPTY, P-FRA, P-TNO1 to P-TN).
O255) indicates the contents of the part as follows.

The table pointer P-DFA is attached to a defective area on the magneto-optical disk D, and is a single part table or a plurality of part tables indicating a track portion (= part) serving as a defective area due to a scratch or the like. The first part table in the box is specified. In other words, if there is a defective part, (01h) to
Either (FFh) is recorded, and the corresponding parts table indicates the defective part by the start and end addresses. If another defective part exists, another part table is designated as link information in the part table, and the defective part is also shown in the part table. If there is no other defective part, the link information is, for example, "(0
0h)]], and there is no link thereafter.

The table pointer P-EMPTY indicates the first part table of one or a plurality of unused part tables in the management table section. If there is an unused part table, the table pointer P-EMPTY is set as the table pointer P-EMPTY. , (01h) to (FFh) are recorded.
If there are multiple unused part tables, the part table specified by the table pointer P-EMPTY is sequentially specified by link information, and all unused part tables are connected on the management table section Is done.

A table pointer P-FRA indicates a writable free area (including an erasing area) on the magneto-optical disk D, and indicates one or a plurality of parts tables indicating parts to be free areas. Of the first part table is specified. That is, if there is a free area, (01h) to (F
Fh) is recorded, and in the corresponding parts table, parts which are free areas are indicated by start and end addresses. When there are a plurality of such parts, that is, when there are a plurality of parts tables, the link information indicates "(00
h)] are sequentially specified up to the parts table.

FIG. 9 schematically shows the management state of parts that are free areas by using a parts table. This is because when the part (03h) (18h) (1Fh) (2Bh) (E3h) is set as a free area, this state follows the table pointer P-FRA and the parts table (03h) (18h) (1Fh) (2Bh) ) (E3h) indicates the state represented by the link. The above-described management of the defective area and the unused parts table is the same.

Table pointers P-TNO1 to P-TNO255 indicate tracks such as songs recorded by the user on the magneto-optical disk D.
In P-TNO1, a parts table indicating a temporally leading part of one or a plurality of parts on which data of the first track is recorded is designated. For example, the track set as the first track is not divided on the disc,
In other words, if recorded in one part, the first
The recording area of the track is recorded as a start and end address in the parts table indicated by the table pointer P-TNO1.

For example, when the music set as the second track is discretely recorded on a plurality of parts on the disc, each part is designated in time order to indicate the recording position of the second track. Is done. In other words, from the part table specified by the table pointer P-TNO2, another part table is sequentially specified by the link information according to the temporal order, and linked to the part table in which the link information is "(00h)". (Same form as in FIG. 9 above). In this way, for example, since all the parts on which the data constituting the second tune are recorded are sequentially designated and recorded, the data of the U-TOC sector 0 can be used to reproduce the second tune or the second tune. When performing overwrite recording on the area, it is possible to access the optical head 3 and the magnetic head 6 to extract continuous music information from discrete parts, and to perform recording using the recording area efficiently.

Next, FIG. 10 shows the format of the U-TOC sector 1. This sector is used as a data area for recording input character information when a track name or a disc name is given to each recorded track.

In the U-TOC sector 1, slot pointers P-TNA1 to P-TNA255 are prepared as character slot indicating data portions corresponding to the recorded tracks, and the slot pointers P-TNA1 to P-TNA255 are provided. Are prepared as slots (01h) to (FFh) in units of 8 bytes and 255 units, and manages character data in substantially the same manner as the U-TOC sector 0 described above.

In the slots (01h) to (FFh), character information as a disc title or a track name is recorded in ASCII code. The 8 bytes immediately before the slot (01h) are a dedicated area for the disc name. Then, for example, the character specified by the user corresponding to the first track is recorded in the slot specified by the slot pointer P-TNA1. Further, by linking the slots by the link information, the character input corresponding to one track can be handled even if it is larger than 7 bytes (7 characters). In this U-TOC sector 1, the slot pointer P-EMPTY manages an unused parts table.

FIG. 11 shows the format of the U-TOC sector 2, which is mainly a data area for recording the recording date and time of the track (or disk) on which the user has recorded. In the U-TOC sector 2, slot pointers P-TRD1 to P-TRD255 are prepared as date and time slot instruction data portions corresponding to each recorded music, and designated by the slot pointers P-TRD1 to P-TRD255. A date and time slot portion is prepared. In the date / time slot part, slots (01h) to (FFh) are formed in units of 8 bytes and 255 units are used to manage date / time data in substantially the same manner as the U-TOC sector 0 described above.

In the slots (01h) to (FFh), the recording date and time of the music (track) is recorded in 6 bytes. Six bytes record numerical values corresponding to year, month, day, hour, minute, and second, one byte at a time. The remaining two bytes are a maker code and a model code, in which code data indicating the manufacturer of the recording device that recorded the music and code data indicating the model of the recording device that recorded the music are recorded. The 8-byte slot immediately before the slot (01h) is an area for recording date and time data for the disk.

For example, when a song is recorded as the first song on a disc, the recording date and time, the maker code and model code of the recording device are recorded in the slot specified by the slot pointer P-TRD1. The recording date and time data is automatically recorded by the system controller in the recording device that performed the recording with reference to the internal clock.

In the U-TOC sector 2, the slot pointer P-EMPTY manages unused slots. For unused slots, link information is recorded in place of the model code, and each unused slot is managed by linking with the link information starting from the slot pointer P-EMPTY.

Similarly to the sector 1, the U-TOC sector 4 is a data area for recording inputted character information when a track name or a disc name is given to a track on which a user has recorded, and the format is as follows. The illustration is omitted because it is almost the same as FIG. However, in this sector, code data corresponding to kanji and European characters are recorded. In addition to the data of sector 1 in FIG. 10, an attribute of a character code used as a character code is recorded at a predetermined byte position. . This UT
The management of the character information of the OC sector 4 is similar to that of the sector 1 by using the slot pointer P-
TNA1 to P-TNA255 and slot pointers P-TNA1 to P-TNA255
255 unit slot (01h) to (FF
h).

As described above, since the U-TOC data is recorded on the disk D, the system controller 11 appropriately displays the disk name, track name, recording date and time and the like read from the disk D together with the reproducing operation on the disk D. It can be displayed on the unit 20.

3. Example of Display Operation of First Display Device An example of the display operation of the display device of the present example mounted on the playback device configured as shown in FIG. 1 will be described. The display device of the present example corresponds to a portion configured by the display unit 20, the display controller 17, the character font 18, the display control function of the system controller 11, and the display mode key in the operation unit 19.

In this example, the display colors of various types of information displayed on the display unit 20 are set according to the display contents. For example, the information on the entire disc D is displayed in red, the information on each track recorded on the disc D is displayed in yellow, and the display on other operating conditions is displayed in green.

Here, the information on the entire disc D is a disc number, a disc name, and a recording date and time of the disc. The disc number is a number set according to the storage position of the storage unit 22 as described above.
The disc name and the disc recording date and time are information read from U-TOC sector 1 and sector 2 of the disc D.

The information on each track recorded on the disk D is a track number, a track name, and a track recording date and time. The track number is the track number in the disk D, that is, the U-TOC
The numbers correspond to the table pointers P-TNO1 to P-TNO255 of sector 0. The track name and track recording date and time are the U-TOC sector 1 and sector 2 of the disk D.
This is the information read from.

Based on such settings, the system controller 11 displays on the display unit 20, for example, FIGS.
The display as shown in (c) is executed. This FIG.
(C) shows a display operation example during reproduction, for example, and the system controller 11 for realizing this display operation.
The processing of (and the display controller 17) is as shown in FIG. 2, for example.

FIG. 3A shows a disc number display 31, a track number display 32, and a time information display 33, which is a reproduction progress time, in which the fifth stored disc D5 is loaded, and one of the fourth tracks D5 is loaded. It is displayed that the position at minute 23 seconds is being reproduced. For example, during reproduction of a certain track, the display mode is set to the track name display mode, and the track name corresponding to the track is displayed. That is, as shown in the figure, "MUSIC BOX" is displayed as the track name display 35, and this is presented as the title of the fourth track of the disk D5.

The processing of the system controller 11 at this time is the processing of steps F101 and F102 in FIG. That is, the disc number display 31 is executed in red, the track number display 32 is executed in yellow, the time information display 33 is executed in green, and the track name display 35 is executed in yellow. Therefore, FIG.
As shown in (a), a track number display 32 surrounded by a broken line
And the track name display 35 turns yellow. For this reason, even if the display of “TRACK NAME” as an auxiliary display in the track name display 35 is small, the character of “MUSIC BOX” is displayed in the same color as the track number display 32. The user can easily recognize the character as a track name.

If the user operates the display mode key at this time, the process proceeds from step F103 to F104, and the display as shown in FIG. 3B is executed by the processes of steps F104 and F105. That is, the disc number display 31, the track number display 32, and the time information display 33 continue in the same manner, but the display mode is set to the disc name display mode, and as shown in the figure, the disc name display 34 is "MARIA CA CA".
REY ”is displayed. Since the disc name display 34 is executed in red, the disc number display 31 and the disc name display 34 surrounded by a dashed line in the figure are displayed in the same color, and the user can determine that the character is the disc name. Easy to recognize.

Further, when the user operates the display mode key from this state, the process proceeds from step F106 to F107, and the display as shown in FIG. 3C is executed in the processes of steps F107 and F108. That is, the disc number display 31, the track number display 32, and the time information display 33 continue similarly, but the display mode is set to the track recording date display mode,
As shown in FIG.
-1 "is displayed. The disc name display 34 is executed in yellow. Accordingly, the track number display 32 and the recording date / time display 36 surrounded by a broken line in the drawing are shown.
Are displayed in the same color. As the information of the recording date and time, U-
The disc recording date and time and the track recording date and time are recorded in the TOC sector 2. When displaying the track recording date and time, the track recording date and time are displayed in the same color as the track number display 32.
The user can easily recognize the contents of the date and time as the track recording date and time.

When the user operates the display mode key from this state, the process returns from step F109 to F101, and
The display of the track name display mode as shown in FIG.

For example, even if the display mode is changed and the display of the track name, the disc name, and the track recording date and time is switched and displayed in the same display area, the track name display 35 becomes the track number display 32. By making the disc name display 34 the same color as the disc number display 31, the user can intuitively determine whether the displayed character is a track name or a disc name. By making the recording date display 36 the same color as the track number display 32, it can be determined that it is the track recording date. Of course, the recording date and time of the disc may be displayed. In this case, the recording date and time is displayed in red of the same color as the disc number display 31, so that the user can recognize the displayed date and time as the recording date and time of the disc.

FIGS. 2 and 3 show examples of changes in the display mode during display and changes in the display state. Of course, other display modes may be used during reproduction. Further, the display mode may be automatically switched by the system controller 11 according to the operation state or the like.

Further, the disc name may be displayed or the recording date and time of the disc may be displayed even during the stop. Also, when the playback order is specified by the program playback setting operation even during stop, the user specifies the track number.In such a case, the track name of the specified track is displayed. You may.

In any case, when the track name and the track recording date and time are displayed, the track number display 32
When the disc name and the recording date and time of the disc are displayed, the disc number display 31 is used.
By using the same color as red, display information can be presented to the user accurately.

4. Second Display Device Example FIG. 4 shows an example applicable to a case where, for example, a full dot color display having a relatively large display area is employed as the display unit 20 of the reproducing device as shown in FIG.

8. Sixth Example of Display Device The above example corresponds to a mini-disc system and mainly makes it easier to understand the distinction between a track name and a disc name. FIG. This is an example in which when information is present, it is possible to clearly distinguish whether the displayed content corresponds to the entire disc or the track.

For example, in a CD text, a disc name, a track name, a lyric writer, a composer, a performer, etc. can be recorded as information accompanying a disc or a track. In FIG. 12, the disc number display 31 and the track number display during reproduction are shown. 32, time information display 33, disc name display 34, track name display 35, lyricist display 3
7, a display example of performing the composer display 38 is shown.

The disc name display 34 is displayed in red along with the disc number display 31 as display information relating to the entire disc. Track name display 35, lyricist display 37, composer display 3
8 is displayed in yellow along with the track number display 32 as the display information for each track recorded on the disk. Time information display 3
3 is green.

As described above, for the display in which it is difficult to distinguish not only the disc name and the track name but also the entire disc or each track, the corresponding relationship is clarified by the displayed color. Therefore, it is possible to realize a display that is easy for the user to see and understand.

9. Various Modifications Although various display examples have been described above, it goes without saying that more various modifications are possible as the present invention. Regarding the display color, the information corresponding to the entire disc is red, the information corresponding to the track is yellow, and the other time information is green, but of course this is only an example, and the color setting is according to the design circumstances. Just do it.

The display of the time information, the reproduction operation mode, etc. may be matched in color as the information corresponding to the entire disc or the information corresponding to the track. For example, as the time information display, in addition to the playback time from the beginning of the track,
The total playback progress time from the beginning of the disc can also be displayed.When the playback time from the beginning of the track is displayed as the time information display, the same color as the track number display is used, and when the total playback progress time is displayed May be displayed in the same color as the disc number.

In a repeat reproduction mode or the like, there may be a case where both a disk repeat for repeatedly reproducing the entire disc and a track repeat for repeatedly reproducing a certain track are enabled. For example, if the character “RPT” is displayed on the display screen in the repeat playback mode, if the “RPT” is being performed during the disc repeat operation,
Preferably, "T" is displayed in the same color as the disc number, and during a track repeat operation, "RPT" is displayed in the same color as the track number. Regarding program reproduction and shuffle reproduction, program reproduction and shuffle reproduction for a disc and program reproduction and shuffle reproduction for a track are conceivable. Therefore, the display color may be changed according to the operation.

In a reproducing apparatus that stores and reproduces one disk instead of the changer type, the disk number is not normally displayed, but the disk name, the total time (the number of recording times and the number of recordable times), It is preferable to display the total reproduction progress time and the like in the same color.

In each example, "DISC NAME"
Auxiliary displays such as "TRACK NAME" are also performed. However, if it is possible to clearly identify whether the display characters are track names or disc names only by color coding, do not execute these auxiliary displays. It may be.

Further, in each example, the mini disk system and C
An example in which the present invention is applied to a D text system has been described. However, the present invention can be widely applied to a reproducing device corresponding to various recording media and a display device mounted on the recording / reproducing device. Of course, the present invention can be applied to a display device mounted on a reproducing device / recording device in which a recording medium is a tape-shaped recording medium other than a disk-shaped recording medium.
