Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a reproducing apparatus,
In particular, audio data can be obtained by reproducing only the main body of a device for reproducing a recording medium such as a CD, MD, or solid-state memory in which song data and control data accompanying the song data are recorded, or by adding a remote control device to obtain audio data. And a reproducing apparatus capable of displaying information based on the control data.

[0002]

2. Description of the Related Art When information is recorded and reproduced on an optical disc as an example of a recording medium, when the disc is an MD, an optical head section and a magnetic field are applied to a recording surface of the MD which is driven to rotate by a spindle motor. A recording / reproducing head, which is a forming head, is positioned, and information recording is performed by magnetic field modulation optical means, and information reproduction is performed by optical means.

That is, at the time of recording, an optical head section is arranged in a non-contact state on a recording surface of a recording disk in a non-contact state, and a magnetic field forming head section is arranged in a substantially contact state on the opposite side of the recording surface to record information. are doing. On the other hand, at the time of reproduction, the magnetic field forming head is completely separated from the surface opposite to the recorded surface of the recorded disk, and the optical head is arranged opposite to the recorded surface in a non-contact state to reproduce information. is there.

Also, during recording, a large current flows through the magnetic field forming head, and a large power consumption is required to further increase the laser power of the optical head. Battery-operated portable disk playback devices must not have the title editing and track editing functions of stationary recording and playback equipment, as well as recording (recording) using an external sound source as a source. Is common.

[0005] Even in the case of a portable disk reproducing apparatus driven by a battery, a circuit designed to reduce the current flowing through the magnetic field forming head unit and a large laser power can be achieved with low power consumption. There is an example in which a recording function is provided by using a circuit that has been used, but since the equipment is likely to be large, a “recording function” is not provided for users who are portable and have almost no chance of recording A reproduction-only disk reproduction device (disk player) is mainly used.

In such a situation, not only when the disc is an MD, but also when the disc is a CD-R or CD-RW, a large power consumption is required at the time of recording, and the size of the disc becomes large. A reproduction-only disk reproduction device (CD player) that does not have a low recording function is mainly used.

[0007] When data is recorded on a disk, music data and control data accompanying the music data are recorded. When a disk on which information is recorded is reproduced by the main body of the apparatus, control data accompanying the recorded music data is recorded. By decoding the data and displaying character data such as "disk name, song name, track number" on a display unit provided in the apparatus main body and / or the remote control device, it is possible to obtain the accompanying information of the currently reproduced music. This is very convenient for actual use on the go, such as in a train.

On the other hand, when the recording medium on which the music data and the control data are recorded is a solid-state memory such as a flash memory card and a smart media, the recording function is provided, not to mention having a reproducing function. The mainstream is to use a read-only device that does not have a recording function because the circuit scale increases and the product price increases accordingly.

[0009]

A conventional reproducing apparatus, especially a reproducing apparatus exclusively for reproducing, does not have a title editing function and a song number editing function of a stationary recording / reproducing apparatus, so that information recording is not performed. When the already-recorded recording medium is played back on the main body of the apparatus, character data such as a song name and a music number are displayed in characters on a display section provided on the main body of the apparatus and / or a remote controller, which is convenient. It is not possible to change, delete, or change the song number of some of the data that has been entered, and if it is necessary, for example, if the “song name” has been entered incorrectly, Must be stored in a memo or the like, and it is necessary to set the recording medium in a stationary recording / reproducing apparatus and edit it, that is, edit the "song name" after returning home from home.
It is complicated and there is a possibility that the possibility of forgetting is high.

[0010] Here, it is only necessary to provide the playback device with an "editing function" for realizing the title editing and song number editing functions of the stationary recording and playback device. It cannot be a practical solution because of problems such as an increase in power and an increase in the size of the device. In particular, when the recording medium is an MD, the control data is stored in the TOC area immediately after the editing. Since writing is performed, if a large vibration or the like is given to the device during the writing, there is a possibility that the writing may not be performed properly due to this, and the edited data may be damaged, and sometimes even the song data may be lost. There is a new problem of being destroyed.

Therefore, an object of the present invention is to enable title editing and song number editing to be performed substantially even with a playback-only playback device, and to correct not only title and song numbers but also song data. It is an object of the present invention to provide a reproducing apparatus that can perform the reproduction in a proper manner.

Therefore, the MD player 1 and the remote controller 2
By operating either the play key 8 or the play key 19, the disc reproducing apparatus comprises, for example, regular reproduction, pause, skip to the beginning of the currently reproduced music, skip to the next music, and skip to the previous music. And various playback operations such as forward fast-forward playback and reverse fast-forward playback.

At this time, the control data b accompanying the currently reproduced music data is output from the ATRAC decoder 12 to the system controller 4, and the control data b is decoded, and the "disk name, music name, track number" And the like are displayed on the display 10 and the display 17.

Here, the user can watch this display while listening to the reproduced music, and can recognize it as reference data of the listened music, which is extremely convenient.

When it is recognized that the display made during such listening is erroneous, changed, deleted or corrected, the editing key 9 of the MD player 1 or the remote control device is used. By operating the second edit key 20, various change data can be created, and the change data is stored in the title edit memory 15 or the track edit memory 16 of the edit data memory 14.

The change data thus stored is
By connecting the MD recorder 3 to the remote control connector C via the remote control cable L after returning home or the like, the data can be corrected on the MD recorder 3 side.

If the change is a title change, the contents stored in the title editing memory 15 are conceptually shown in, for example, "Disc number, applicable track number, title editing type, title data" as shown in FIG. The data of each item is stored.

That is, the disc number is a number assigned to the disc whose title is to be changed. The corresponding track number is
This is the number of the track having the title to be changed. The title editing type depends on what kind of change it is,
"Rewrite, replace, partially correct, delete, delete all, delete part" and the like.

For example, when rewriting all of the titles already assigned to the song whose disc number is 1 and the corresponding track number is 024, the item of the disc number is "00".
"1", the item of the corresponding track number is "024", the item of the title editing type is "rewrite", and new character data to be newly created is stored in the item of the title data.

In the case of "replacement", the item of the disk number is "001" and the item of the corresponding track number is "00".
4,007 ", the title edit type is set to" replacement ", and no data is stored in the title data, and the data stored in the edit data memory 14 is input to the MD recorder 3 later. As a result, the character data with the disk number "001" and the track number "004" are replaced with the character data with the track number "007".

Similarly, in the case of "partial correction", the character address to be deleted and the new character data are stored to correct the character. For example, when the spelling in the title character is incorrect, the corresponding character is corrected. be able to. In addition, the title of a specific track can be “deleted”, the titles of all tracks can be “deleted entirely”, and only the extra characters can be “partially deleted”.

On the other hand, the operation key 7 provided on the MD player 1 or the edit key 20 provided on the remote controller 2
If the change command issued by the user is a track change, the track edit memory 1 of the edit data memory 14
For example, as shown in FIG. 3, which conceptually shows the stored contents of No. 6, data of each item of "disk number, corresponding track number, track edit type, other data" is stored.

That is, the disc number is a number assigned to the disc to be track-edited.
This is the number of the track to be changed, and the track edit type includes "delete, replace, move, combine, split" and the like depending on what kind of change is made. The track editing type also includes "volume correction" for changing the recording volume level of the reproduced music data, and "sound quality correction" for changing the recording sound quality of the reproduced music data.

For example, the track with the disk number 1 and the track number 001 is "deleted", the track with the disk number 1 and the track numbers 004 and 002 is "swapped", Is 00
Track 9 is “moved” between “previous track number” and “backward track number”, or track numbers 011 and 0
Twelve tracks can be “joined” into one track, or track number 005 can be “split” based on “segment point address” data.

The recording volume of the track having the track number 001 with the disk number 009 is increased by +3 dB, or the volume of the track having the disk number 009 is simultaneously specified (001 and 007). "Volume correction" to increase the recording volume of both tracks by + 6dB
Or "volume correction" to reduce the recording volume of all tracks of one disk number by -6 dB, or to change the sound quality of the specific track (012) of the specific disk number (256) at the time of recording from 0.5 to 6 kHz. Or "sound quality correction" to increase the band of +6 dB.

It should be noted that various editing change data created by the editing key 9 or the editing key 20 are shown in FIGS.
This is just an example, and it can handle very wide variations such as changing the already recorded "Hiragana title" to "Katakana title" or changing "Full-width character" to "Half-width character". Needless to say, even when a text-compatible CD is reproduced and the music data is copied to the MD together with the text, the correction can be performed.

The disk reproducing apparatus having the above-described configuration has
FIG. 4 shows a “data transfer unit” configured to transfer the data of the edit data memory 14, that is, the data of the title edit memory 15 and the track edit memory 16 to the MD recorder 3 using the remote control cable L. As shown in the figure, a disc reproducing apparatus is composed of an MD player 1 and a remote controller 2, a writing device 1a provided internally or externally in the main body of the MD player 1 is provided, and an MD recorder 3 (external device) is provided. And a card type memory 21 such as a flash memory in which editing change instruction data is written by the writing device 1a. The data recorded in the memory 21 is read by the reading device 3
The “data transfer unit” may be configured to be able to read by “a”.

The above-described disk reproducing apparatus is an example in which the present invention is applied to a case where the recording medium is an MD. However, it is applicable to a case where the recording medium is a CD or a solid memory such as a flash memory or a smart media. Of course, it is also good.

[0051]

As is apparent from the above description, the playback apparatus according to the present invention is displayed regardless of whether it has a title editing or song number editing function of a stationary recording / reproducing apparatus. It is possible to change or delete some of the characters such as titles, etc., or to change the song number when necessary. By performing data transfer with respect to the type of recording / reproducing apparatus, it becomes substantially equivalent to having an "editing function".

Furthermore, the additional components provided to implement the title editing and song number editing functions of the stationary recording / reproducing device are mainly composed of the editing data memory, so that the power consumption increases. And the problem of equipment enlargement does not occur.

Therefore, according to the present invention, it is possible to substantially perform title editing and song number editing even with a playback-only device, and to substantially correct not only titles and song numbers but also song data. A playback device that can perform the playback.
