Abstract

PURPOSE: A method for a user memo of an optical magnetic recorder is provided to add an electronic note function to an optical magnetic recording system by assigning a UTOC area for a memo function. CONSTITUTION: If a memo key is inputted, the current state of a UTOC(User Table Of Code) is searched in a memo mode to discriminate whether memo is possible(102-105). According to the state of the UTOC, the current state is displayed and a wait mode is executed to decide whether data is inputted or displayed(106-108). During the wait mode, information is inputted by a user input key(109-110). A user inputs a memo mode release key(113). It is searched whether a stop key is inputted(101). It is searched whether the UTOC has changed(115). If so, the change is recorded(116). Otherwise, an optical magnetic recorder is stopped(117).

Description

User memo method of magneto-optical recording device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user memo method in which a magneto-optical recording apparatus can record character information required by a user using a part of a user table of code (UTOC) in a data recording area.

1 is a configuration diagram of a conventional magneto-optical recording device.

The conventional magneto-optical recording device has a magnetic head 1, a spindle motor 3, a control signal driver 4, a recording driver 5, an optical pickup 6, a laser controller 7 as shown in FIG. ), Slide motor (8), address decoder (9), RF amplifier (10), EFM ACIRC encoder / decoder (11), memory (12), shock-proof memory controller (13), system The control unit 14 includes an ATRAC encoder / decoder 15, an input / output driver 16, a display unit 17, and a key input unit 18.

The operation of the conventional magneto-optical recording device configured as described above will be described.

First, the reproducing operation of the magneto-optical recording device will be described.

There are two types of discs, a reproduction-only disc and a recording disc. First, the reproduction mode of the RF amplifier 10 is set by determining whether the disc is exclusively for reproduction or recording.

The disk read signal converted from the optical pickup 6 to the I / V is input to the RF amplifier 10 and processed according to the type of the disk, and input to the EFM signal of the EFM ACIRC encoder / decoder 11, which is a digital signal system. The EFM signal is demodulated and decoded by an internal digital PLL signal in the EFM ACIRC encoder / decoder 11 and input into the shock-proof memory controller 13 in a data format after error correction is performed EFM ACIRC encoder / decoder 11 The signal outputted from the is decoded by the shock-proof memory controller 13 and stored in the memory 12, and the disk is intermittently controlled in accordance with the state of the memory 13.

In addition, the data stored in the memory 12 is transmitted to the ATRAC encoder / decoder 15 by one cluster according to the request, stretched and synthesized according to the L / R (Left / Right) channel, and then input / output driver ( 16). The signal input to the input / output driver 16 is transmitted to the output device as audio information by the D / A converter of the input / output driver 16.

It is also possible to output a digital output signal output from the ATRAC encoder / decoder 15 for ATRAC digital output.

Next, the recording operation of the magneto-optical recording device will be described.

When the analog signal is input from the line input and the microphone input, the input / output driver 16 performs appropriate signal processing and outputs the audio digital signal output from the A / D converter to the ATRAC encoder / decoder 15. The ATRAC encoder / decoder 15 compresses the data output from the input / output driver 16 in accordance with a compression algorithm and outputs it to the shock-proof memory controller 13.

Also, if digital input data can be recorded in accordance with SCMS, it is compressed by ATRAC and input to the shock-proof memory controller 13.

The compressed data input to the shock proof memory controller 13 is stored in the memory 12 in the shock proof memory controller 13 and encoded in the MD format under the control of the system control unit 14 to process digital signals one by one. The system is input to the EFM ACIRC encoder / decoder 11 which is a system, decoded and signalized by the EFM, and then output to the recording driver 5 as an EFM signal.

The EFM signal input to the recording driver 5 applies a magnetic field to the magnetic head, and is controlled by the control signal driver 4 to control the spindle motor 3 and the slide motor 8 and irradiate the laser spot from the optical pickup 6. Magnetic field modulation is overwritten and recorded at a position on the disk.

Conventional magneto-optical recording devices generally have a function of editing a song name, disc name, recording date and time, separating and compositing, and deleting a song by using an editing function. If necessary, the song name, disc name, recording date and time can be displayed. There is a convenient function, such as song search, section repeat play, song repeat play, and many other features are added.

However, the conventional portable magneto-optical recording device has a disadvantage in that when a user simply inputs a simple memo or song lyrics, the user cannot see it when necessary.

An object of the present invention for improving the above disadvantages, in the magneto-optical recording apparatus, by using an empty user area (e.g., UTOC (Usertable of Contents area in the case of a mini-disc)), such as a schedule, telephone number, etc. It is to provide a user memo method to have a memo function.

Another object of the present invention is to provide a user memo method for extending a function of a portable magneto-optical system by adding input functions such as lyrics of a song required by a user.

In order to achieve the above object, according to the present invention, when a memo key is input by a user's request in a general reproducing operation state of the magneto-optical recording device, the memo mode is switched to determine whether memo is possible by searching the current user area in the memo mode. Limit of memo mode input execution, wait mode waiting for data input or display while displaying the current status according to user area status after memo mode execution step, display displaying information input by key input In the performing step, when data is input in the weight mode, a data input performing step of inputting corresponding data into a user area is provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a configuration diagram of a mini disc system which is an example of a magneto-optical recording apparatus to which the present invention is adapted.

The mini disc system to which the present invention is applied has a magnetic head 1, a spindle motor 3, a control signal driver 4, a magnetic head driver 5, an optical pickup 6, a laser as shown in FIG. Controller 7, sled motor S, address decoder 9, RF amplifier 10, EFM ACIRC encoder / decoder 11, memory 12, memory controller 13, system controller 14, It consists of an ATRAC encoder / decoder 15, an input / output driver 16, a display unit 17, a key input unit 18, and a sub memory 19.

That is, the magneto-optical recording apparatus according to the present invention is constructed by adding a sub memory 19 to the conventional magneto-optical recording apparatus.

3 is a flowchart showing an embodiment of a user memo method according to the present invention, and records and reproduces simple contents desired by a user to provide a function of an electronic notebook to a user.

First, when a memo key is input in the normal reproducing operation state, the memo mode performing steps 102 to 105 determine whether a memo is possible by searching the state of the current UTOC in the memo mode.

Perform memo mode performing steps 102-107. That is, when a memo key is input in the normal reproducing operation of the magneto-optical recording device, the memo mode is entered to search whether the UTOC is available for memo (102, 103, 104). Display and proceed to the normal playback operation state (105). After the memo mode input step, the user performs the weight mode execution step 106-108 of waiting for whether to input data or display data while displaying the current status according to the UTOC state. That is, if the search result UTOC is available for notes, it searches for the UTOC already used for notes (106), and if the UTOC has already been used for notes, displays the purpose of the memoized UTOC, i.e. the title of the memo. In step 107, the user waits for a key input from the user (108), and performs data input step (109-110) of inputting information by the user input key while performing the weight mode.

That is, when a data input key is input (108), a desired data, for example, a telephone number is received through a key input unit and input to the UTOC (109). If an error occurs during data input (110), an error message is output (111), and the process proceeds to searching whether a memo release key is input.

In addition, while performing the data input, the input completion key is checked, and when the input completion key is input, the process proceeds to the step of searching whether the memo release key is input (112). If the input completion key is not input, the process returns to the input mode 109 and continues input (109, 110, 112).

If the input is completed normally, the already entered information can be modified. You can edit the data as you search for it.

In addition, if a display key is input during the execution of the weight mode, the display mode performing step 114 of displaying memo data of the UTOC is performed. In the display mode, the data already input by the user is output through the display unit so that the user can use it. That is, when a phone number is input, various functions of searching for and displaying necessary information using a person's name or a phone number or scrolling in turn are displayed.

In the memo mode release step, a memo mode release key is input from the user (113).

If the release key is not input, the process proceeds to the weight mode 108 to continue data input (109, 110, 111, 112), or enters the display mode (114).

When the release key is input, the memo mode is canceled and the process proceeds to the normal play mode 100.

If the stop key is input during the normal play mode, and if there is an input of the stop key (101), if there is a change in the UTOC, it is recorded and if it is not recorded, it stops as it is (115, 116, 117).

4 is a flowchart illustrating another embodiment of the UTOC memo method according to the present invention. When a memo recording amount is large by using a sub memory for the memo function, one of the UTOCs which are not used is selected as a memo management UTOC to manage an address. do.

For example, it provides a convenient function that allows users to enter the lyrics of a recorded song and read it when needed.

UTOC recording step (200,201,221,222,223) for recording according to the change of UTOC (User Table Of Code) in the normal reproducing operation state of the magneto-optical recording device, and memo mode performing step for retrieving the status of the current UTOC in memo mode when memo key is input 202-207 is performed in the same manner as in the embodiment of the UTOC memo method of FIG.

The input mode execution step is performed as follows.

When the data input key is input, the desired data is input to the sub memory (208, 209, 210), and when recordable data is accumulated in the sub memory, the data is written to an address that can be used by the UTOC. (211,212,213). Repeat step (208, 209, 210) of inputting data into the sub memory until the data input is completed (214), search whether the memo mode release key is input (215), and when the memo mode release key is input, proceed to the normal playback operation state. If the memo mode release key is not input, data is input (208, 209, 210).

That is, the character information input by the user is written in the sub memory, and the recordable information is accumulated in the memory, or when the input completion signal is input, the character information is written in the address that can be used by the UTOC. After writing to the disc, write to the disc. At this time, if the memo release key is inputted, it proceeds to the normal playback operation state.

In addition, the display mode performing step is performed as follows.

The system operates to read the memo address required from the UTOC from the UTOC, and in response, reads and displays data from the sub memory.

That is, while the system is operating, data is first read from the address related to the current song from the memo management UTOC and stored in the sub memory, and the stored data is displayed to the user through the display unit.

When the user inputs a memo release command through the key input unit to exit from the input mode or the display mode, the user proceeds to the normal play mode, and continues with the current mode.

If the stop key is input during the normal playback operation, the UTOC is recorded according to the presence or absence of the UTOC data change, and data is read from the sub-memory at the address recorded in the UTOC, and then stopped (221, 222, 223).

As described above, the present invention allocates the UTOC area not used in the conventional magneto-optical system for the memo function, gives a simple memo function to the allocated area, or inputs a large amount of data to call the user when necessary to confirm or It is convenient and useful because it allows the modification to add the electronic organizer function to the magneto-optical system.
