Abstract

A data recording method using a hard disc is provided to reduce a recording time after data are reproduced by selectively activating a temporary file area of a recording medium, storing reproduced data, and copying the data stored in the temporary file area in a main area according to a recording request. A microcomputer activates a temporary file area of a hard disc according to the reproduction request of external data(S200,S202). The microcomputer reproduces the external data according as the temporary file area is activated, and records the reproduced external data in the temporary file area(S204-S212). After the reproduction of the external data is completed, the microcomputer judges whether the recording of the external data is requested(S212,S214). When the recording of the external data is requested, the microcomputer copies the external data recorded in the temporary file area in a main area of the hard disc and deletes the external data recorded in the temporary file area(S216,S218).

The present invention relates to a data recording method, and more particularly to a data recording method using a hard disk that can reduce the recording time.

In general, two or more different devices connected to one integrated system are called combination systems or combo systems. An example of a combination system is a digital recorder combo system combining a digital recorder function with a hard disk device.

Here, the optical disc loaded into the digital recorder includes a DVD-ROM for playback only, a DVD-R that can be recorded once, a rewritable DVD-RAM, or a DVD-RW.

In such a digital recorder combo system, high quality video or high quality audio data is recorded, that is, high quality video or high quality audio data is stored on a hard disk or loaded on an optical disc loaded in a digital recorder.

The above-mentioned combo system has a built-in tuner, and has a function of receiving a broadcast program and storing the received broadcast program on an optical disk or a hard disk.

Hereinafter, a process of storing data stored in a broadcast program or an optical disk in a hard disk by a conventional combo system will be described below.

First, in a method of storing a broadcast program on a hard disk, a broadcast program for an arbitrary channel is stored on the hard disk by tuning to an arbitrary channel to receive the broadcast program and then operating a recording key.

Next, in the method of storing the data stored on the optical disk on the hard disk, the data stored on the optical disk can be copied to the hard disk by operating the optical copy or recording key.

However, if the user wants to copy data stored on the optical disk to the hard disk while the optical disk is playing, the data stored on the optical disk can be hardened by playing the optical disk again from the beginning and operating the copy key or the recording key. There is a problem that the copy time is long during optical disc reproduction because it can be copied to a disc.

In addition, in the case of a broadcast program, since there is no method for recording from the beginning during viewing, there is a disadvantage in that only a re-broadcast can be recorded.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a problem of the prior art, and in addition to reproducing, selectively activates a temporary file area of a recording medium to store data to be reproduced, and then stores the data stored in the temporary file area according to a recording request. The present invention provides a data recording method using a hard disk that can reduce recording time after data reproduction by copying to a main area.

In order to achieve the above object, the present invention provides a data recording method of a recording and reproducing apparatus for recording or reproducing an external data by MPEG signal processing, the method comprising: a) the hard disk in response to a request for reproducing the external data; B) reproducing the external data according to activation of the temporary file area, and recording the reproduced external data in the temporary file area; and c) Determining whether there is a recording request for the external data after the reproduction is completed; and d) copying the external data recorded in the temporary file area to the main area of the hard disk when the recording request is received. And deleting the external data recorded in the.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a data recording and reproducing apparatus having a hard disk according to the present invention.

Referring to FIG. 1, a data recording and reproducing apparatus includes an MPEG unit 100, a hard disk 102, a recording medium managing unit 104, a key input unit 106, and a microcomputer 108.

The MPEG unit 100 receives external data, for example, a broadcast data stream, data reproduced by an optical disk reproducing apparatus, etc., receives the MPEG signal, provides the MPEG signal to the HDD 110, or hardly controls the microcomputer 104 under the control of the microcomputer 104. Data received from the disk 110 or external data is processed by MPEG signal processing and played through a TV.

The hard disk 102 is divided into a main area 102a and a temporary file area 102b. When external data is reproduced, the MPEG signal processed data provided from the MPEG unit 100 is transferred to the temporary file area 102b. Save it. At this time, if there is a recording request after the external data reproduction is completed, the data stored in the temporary file area 102b is copied to the main area 102a.

The recording medium management unit 104 fetches the data to be recorded in the temporary file area 102b and copies it to the main area 102a when there is a recording request from the user after playback ends under the control of the microcomputer 108. .

The key input unit 106 includes a plurality of function keys for controlling the functions of the data recording apparatus, and applies a corresponding key signal to the microcomputer 108 according to the operation of the function keys.

The microcomputer 108 controls the overall functions of the data recording and reproducing apparatus. In particular, the microcomputer 108 displays an OSD screen on the display device, not shown, which asks whether external data is played and whether the temporary file area 102b is activated. By activating the temporary file area 102b based on the selection, the temporary data area 102b is stored in the MPEG signal-processed data temporary file area 102b along with the reproduction of the external data.

In addition, when the temporary file area 102b is activated, the microcomputer 108 checks the remaining capacity of the temporary file area 102b and then, when the remaining capacity falls below a preset reference capacity, the microcomputer 108 deletes the data stored in the temporary file area 102b. After deletion, the temporary file area 102b is activated.

When the microcomputer 108 receives a key signal corresponding to the recording key from the key input unit 106 after the reproduction is completed, the microcomputer 108 drives the recording medium management unit 104 to store data stored in the temporary file area 102b of the hard disk 102. Only the data to be recorded by the user is extracted and copied to the main area 102a of the hard disk 102. Here, the data copied from the temporary file area 102b to the main area 102a will be deleted.

A process of recording data by the data recording and reproducing apparatus having the above configuration will be described with reference to FIG.

2 is a flowchart illustrating a process of recording data using a hard disk according to a preferred embodiment of the present invention.

First, referring to FIG. 2, when a key signal corresponding to a playback key is applied from the key input unit 106, the microcomputer 108 enters a playback mode and asks whether the temporary file area 102b is activated. Is displayed on the display device (S200, S202).

Thereafter, when the user wants to activate the temporary file area 102b in step S202, the microcomputer 108 searches the hard disk 102 to calculate the remaining capacity of the temporary file area 102b (S204).

Thereafter, the microcomputer 108 compares the remaining capacity of the temporary file area 102b with the reference capacity to determine whether the remaining capacity is less than or equal to the reference capacity (S206).

As a result of the determination in step S206, when the remaining capacity is equal to or less than the reference capacity, the microcomputer 108 deletes the data stored in the temporary file area 102b (S208). At this time, the microcomputer 108 may delete only some of the data stored in the temporary file area 102b, and some of the data is the oldest data based on the stored time.

Subsequently, the microcomputer 108 controls the MPEG unit 100 to process and reproduce the external data by performing MPEG signal processing on the MPEG unit 100, and the MPEG signal processed data is stored in the temporary file area 102b of the hard disk 102. Save it (S210).

On the other hand, as a result of the determination in step S206, when the remaining capacity exceeds the reference capacity, the microcomputer 108 proceeds to step S210.

As described above, while reproducing the external data and storing the temporary data in the temporary file area 102b, the microcomputer 108 determines whether a key signal corresponding to the reproduction end key is input from the key input unit 106 (S212).

As a result of the determination in step S212, when a key signal corresponding to the reproduction end key is input, the microcomputer 108 copies a key signal for copying data stored in the temporary file area 102b from the key input unit 106 to the main area 102a. It is determined whether is input (S214).

As a result of the determination in step S214, when a key signal is input, the microcomputer 108 controls the recording medium management unit 104 to copy the data reproduced in step S200 from the data stored in the temporary file area 102b to the main area 102a. After that, the data in the temporary file area 102b is deleted (S216 and S218).

In the preferred embodiment of the present invention, the data reproduced according to the recording request is fetched from the temporary file area 102b and copied to the main area 102a. However, in another embodiment, the microcomputer 108 may store the temporary file area ( 102b) retrieves the data stored in the OSD screen to select at least one or more, and as the user selects at least one or more data control the recording medium management unit 104 to convert the selected data (s) to a temporary file area ( After withdrawing from 102b, it is copied to the main area 102a and then the selected data (s) are deleted from the temporary file area 102b.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

As described above, the present invention selectively activates the temporary file area of the recording medium in addition to playback to store the data to be reproduced, and then copies the data stored in the temporary file area to the main area according to a recording request. You can reduce the recording time.
