Abstract

PROBLEM TO BE SOLVED: To make a title name easy to see and to make possible displaying a full name of a long title by inserting a specified character among plural characters when a long title name is inputted to a disk, discriminating the specified character at a reproducing time and separately displaying its before/ behind characters. SOLUTION: When a user inputs a music name and a singer name as a track name to a prescribed track number TNO, the user inputs the specified character '/' between the music name and the singer name. At the reproducing time, when the user performs track selection of its TNO by a key matrix 7, a system controller 5 discriminates the presence of the character '/'. and when it exists, the controller 5 displays the music name to a first row on a display device 8, and displays the singer name to a second row. At this time, the '/' isn't displayed as discriminative information. Thus, even the longtitle name inputting the music name and the singer name is visualized simultaneously, and handleability is improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk reproducing apparatus for reproducing a disk, for example, a mini disk (MD).

[0002]

2. Description of the Related Art Conventionally, in a disc reproducing apparatus for reproducing a disc, for example, an MD, on which a track name corresponding to, for example, a track number (TNO) is recorded as a title name, when the MD is reproduced, the track name in one TNO is read. The display is displayed on a one-line display (for example, a liquid crystal display), and the number of segments on the display is limited. If a song name and a singer's name are entered as a track name, the number of characters increases. Usually the singer's name part in the latter half is not displayed at the same time, but must be scrolled and displayed. As an example, as shown in FIG. 4, in the case of a one-line display capable of displaying twelve characters consisting of characters and symbols, for example, a track name "001 escalation / tomosakarie"
In most cases, even if nine characters (including spaces) are input, the characters protrude from the display unit D.

[0003]

However, in this case, even if the title of the song and the name of the singer are entered, all of them are not displayed, and most of them are only seen for a moment when scrolling for the first time, and are difficult to confirm.

An object of the present invention is to solve the above problems,
It is an object of the present invention to provide a disc reproducing apparatus with an improved title name display.

[0005]

SUMMARY OF THE INVENTION A disk reproducing apparatus according to the present invention is a disk reproducing apparatus for reproducing a disk on which a title name is recorded.
Discriminating means for discriminating a specific character among a plurality of characters constituting the title name; and, based on a discrimination result of the discriminating means, the title name is divided into a character part before the specific character and a character part after the specific character. And display means for separately displaying.

[0006] Further, a disc reproducing apparatus according to the present invention comprises:
The display means displays the title name before and after the specific character on separate lines based on the result of the determination by the determination means.

[0007] Further, a disk reproducing apparatus according to the present invention is characterized in that:
The disc is a mini-disc.

[0008] Further, a disc reproducing apparatus according to the present invention comprises:
The title name is the track name corresponding to the track number.

[0009] Further, a disk reproducing apparatus according to the present invention comprises:
The title name is the disc name.

[0010]

When a disc on which a title name is recorded is reproduced by a disc reproducing apparatus, a specific character among a plurality of characters constituting the title name is determined, and the title name is determined from the specific character based on the determination result. The preceding character portion and the following character portion are displayed separately (for example, by changing lines). Therefore, when it is desired to input a long title name, all of the title names can be displayed by inserting a specific character, which makes it easy to view and easy to use.

[0011]

FIG. 1 is a block diagram showing an MD reproducing apparatus which is an embodiment of a disk reproducing apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes an RF matrix amplifier,
Processes RF signals and servo signals used for recording and reproduction of MD. The RF matrix amplifier 1 includes a focus error signal and a tracking error signal necessary for controlling the focus and tracking of the optical pickup assembly 11, and an FM modulation signal of ADIP (ADress In Pregroove) which is address information of a recordable MD recording area. To the servo and EFM / ACIRC encoder / decoder 2. The RF matrix amplifier 1 also includes an APC circuit for keeping the amount of emitted laser light constant.

Reference numeral 2 denotes a servo, EFM / ACIRC encoder / decoder, and a servo controller and an EFM / ACIRC.
And a C encoder / decoder unit. The servo control unit receives a focus error signal and a tracking error signal from the optical pickup in the RF matrix amplifier 1 and receives a focus servo signal and a tracking servo signal of the optical pickup, and further, a disc motor control servo signal and an address from the ADIP signal. The information is taken out, the optical pickup and its feeding mechanism are controlled, and the rotation of the disk is controlled.

At the time of encoding, the EFM / ACIRC encoder / decoder unit uses an ATRAC (Adaptive TRansfo
ADC (Analog-Digital Converter) 1 encoded by rm Acoustic Coding encoder / decoder 3
ACIR of the audio input signal converted from A / D
An error correction code is added using C, EFM modulated, and output to the optical pickup assembly 11. At the time of decoding, the EFM signal input from the RF matrix amplifier 1 is EFM-demodulated, error-corrected by ACIRC, and
Output to ATRAC encoder / decoder 3. This signal is ATRAC decoded, and the DAC (Digital-Analog
Converter 9 converts the signal into a digital audio output signal.

Reference numeral 3 denotes an ATRAC encoder / decoder, which compresses and decompresses audio for MD recording and reproduction. here,
The voice compression data is compressed to about 1/5 of the original data, and the rotation speed of the MD is about 5 times or 1 times as large as the input and output amount of data because the rotation speed of the MD is the same as the specified speed of the EFM.
Therefore, a DRAM 4 called a shock-proof memory is used as a data buffer. Reference numeral 5 denotes a system controller composed of a microcomputer or the like, which issues an instruction to the RF matrix amplifier 1, the servo, and the EFM / ACIRC encoder / decoder 2 to perform normal reproduction, recording, pause, stop, search, and the like. Also, the servo and EFM / ACIRC encoder / decoder 2 output the TOC recorded on the MD.
UTOC information and address information, and decodes and generates time display data.

Reference numeral 6 denotes a memory, which stores the MD of the TOC and UTOC information received via the system controller 5.
Stock of management information necessary for playback of tracks, display of title names such as track names and disc names, etc.
Read and write when necessary. Reference numeral 7 denotes a key matrix which receives an instruction from a user's key operation and controls the system controller 5 to control normal reproduction, recording, pause, stop, search, etc., read and write to the memory 6, request display on the display 8, etc. Perform Reference numeral 8 denotes a display. In this example, as shown in FIGS. 2 and 3, the display 8 is a two-line display capable of displaying 12 characters including characters and symbols.

On the other hand, in the UTOC area sector 0 of the sector format used in the MD, management information of recorded music data, TNO, and the like are recorded.
In the OC area sector 1, character information indicating a title name such as a disc name and a track name is recorded. Therefore, when reproducing the MD, the music data is reproduced based on the address information of the program area in which the music data for each TNO described in the UTOC area sector 0 is recorded, and at the same time, the music data is reproduced in the UTOC area sector 1. The contents can be displayed on the display 8 based on the information of the track name and the disc name corresponding to each TNO.

At the time of recording on the MD, the start and end address information of the music information recorded on the program area is recorded in the UTOC area sector 0 in association with the TNO, and the input disc name / track name is recorded. Information is recorded in UTOC area sector 1 in association with TNO.

Then, the user enters a song name (eg, "escalation") as a track name in TNO 001.
And the singer's name (for example, "Tomosakarie")
A specific character "/" (ASCII code 2FH) is input between the song name and the singer name.

At the time of subsequent MD reproduction, the user
When track selection of 001 is performed by the key matrix 7, the system controller 5 determines the presence or absence of a character code representing the character "/" in the track name, and when a determination result that this character code exists is obtained. As shown in FIG. 2, the first line of the two-line display 8 displays the character portion before "/", that is, the song name portion, and the second line displays the character portion after "/".
That is, the singer's name is displayed. Note that “/” is used as discrimination information and is not displayed on the display unit of the display device 8. Therefore, the input song name and singer name can always be viewed at the same time during MD playback, improving usability.

[0020]

When the track name cannot be found in the track name in the pre-mastered MD or the like or when the user does not enter "/" at the time of input by the user, the system controller 5 sets the track name in the track name. It is determined that there is no character code representing the character "/" in
Based on the determination result, as shown in FIG. 3, the track name can be displayed on the first line, and other display contents other than the track name, for example, time can be displayed on the second line.

Further, in the above example, the specific character is "/", but other characters may be used. For example, a plurality of character strings such as “* / *” are possible. This is to prevent the display from becoming abnormal at "/" when the album is 1/2 or 2/2.

In the above example, the case where the title name is a track name has been described. However, the present invention can be similarly implemented when the title name is a disc name.

In addition to the MD, the present invention can be applied to all discs in which title names can be input.

As described above, when displaying various title names, the character information can be displayed in an easily viewable manner within a fixed display area of the display. Also, in the case of hard copy (paper or the like) such as label printing of an MD and label printing of a cassette, it becomes very easy to see by implementing the present invention.

[0025]

According to the present invention, it is possible to obtain a disc reproducing apparatus capable of displaying a title name which is easy to see and easy to use.
