    The present invention relates to a method of playing a bad CD, and in particular, when a CD is mounted in a predetermined CD player, the CD kit 10 starts reading data, and determines whether or not normal data is read by the CPU 30 of the CD player. In this case, if the normal data is read, the contents of the CD are displayed through the video / audio output unit 60, but if the normal operation is not performed, read the data again and determine whether the normal data is read once more, and then read the normal data. If not, read the data by moving the current position 5 seconds from the current position, it is determined whether the normal data is read again, and if the normal data, including the method of displaying the contents of the CD through the video / audio output unit 60 The present invention is characterized in that the defect of the CD, that is, the outside of the CD When you want to read a large part of the data, such as a fingerprint or a fingerprint, read the data once more and when the data does not read normally, you can play the CD normally by reading the data in the back.

    How to play bad CD
    The present invention relates to a compact disc (hereinafter referred to as a CD) player. In particular, when using a video CD player that is generally used for a long time, a lot of gas is generated on the surface of the CD, and normal playback is impossible. Many of them relate to a bad CD playback method that can play a CD normally by skipping and reading data from the next part.
    As is well known, the PCM recorder was first introduced as a digital audio device in 1968, but before that, the Bell Labs and MIT of the United States had been studying digital recording and playback of wideband voice signals by computer. With the release of CDs in 1982 and the popularity of audio fans, digital signal processing has developed at a significant pace, and digital records have made it possible to economically and long-term preserve large amounts of information.
    In the development of digital technology, recording and reproducing technology has been relatively smoothly developed from the computer's external memory device, magnetic tape and magnetic disk, and has accelerated the development of coupling with digital audio. In Korea, SKC entered CD in full-fledged era of digital audio in 1986 by producing CD in cooperation with Philips, and it is now an important part of audio.
    However, the conventional CD player device as described above cannot reproduce the CD properly when there is a scratch on the outside of the CD or the fingerprint is generated outside the CD, and an error occurs in the system itself when a lot of data is input therein. There was this.
    The present invention is to solve the above-mentioned conventional problems, in the conventional CD reading method, if a defective portion caused by a gas or fingerprint on the CD provides a method that can read the CD beyond the defective portion. Its purpose is to.
    In order to achieve the above object, in the bad CD reproducing method of the present invention, when a CD is mounted in a predetermined CD player, data is started to be read, and it is determined whether normal data is being read by the CPU of the CD player. If it is, the contents of the CD are displayed through the video / audio output section.However, if it is not in normal operation, the data is read again and it is determined whether it is reading normal data once more. After reading, it is determined whether normal data is read again, and if normal data, the contents of the CD are displayed through the video / audio output unit.
    1 is a functional block diagram showing an apparatus for playing a bad CD according to an embodiment of the present invention;
    2 is a control flowchart illustrating a method for playing a bad CD according to an embodiment of the present invention.
    <Explanation of symbols for main parts of the drawings>
    10: CD Kit 20: Key Input
    30: CPU 40: RAM
    50: ROM 60: Video / Audio Output
    70: display unit
    Hereinafter, the above-described contents will be described in detail through an embodiment according to the present invention.
    As shown in FIG. 1, first, the CD kit 10 is a part for reading data when an unspecified CD to be read by a user is mounted in a predetermined CD player, and the key input unit 20 is the CD kit. 10 is a part for operating a CD mounted on the (10) or a button for other operations, the CPU 30 is a portion for performing or processing the input from the key input unit 20, RAM 40 is The temporary data generated during program processing is stored, and the ROM 50 stores all programs executed or processed by the CPU 30, and the video / audio output unit 60 processes the contents processed by the CPU 30. Outputs video and audio, and the display unit 70 configures this embodiment to show the user all the situations while the CD player is playing.
    In addition, as shown in FIG. 2, the present invention first starts reading data when a CD is mounted in a predetermined CD player, and determines whether normal data is being read by the CPU 30 of the CD player. Read the data through the video / audio output unit 60, but if it is not in normal operation, reads the data again and determines whether it is reading normal data once more; If the normal data is not read in the data checking step 100, the data is read from the current position by 5 seconds, and then the normal data is read again. If the normal data is read, the video / audio output unit 60 is used. This embodiment includes a data reading step 200 in which the contents of the CD are displayed.
    Hereinafter, the operation of the bad CD playback method configured as described above will be described in more detail with reference to the accompanying drawings.
    First, when an unspecified person wants to read data in a CD with a predetermined CD, when a CD player disk is put on, the CD kit 10 mounted inside the CD player is operated due to the key operation of the key input unit 20. The data is read.
    The data read from the CD kit 10 is set by the CPU 30 by the initial program, and after reading the data, the CPU 30 determines whether the data read from the CD kit 10 is normal. If it is data, the rest of the data is read.
    If it is determined that the CPU 30 is not normal data, the CD kit 10 reads the data again, and then the CPU 30 determines whether the normal data is read once again and reads the normal data. It will read the data of (100).
    However, if it is determined that the normal data is not read, the CPU 30 reads the data after moving it from the current position for 5 seconds, and then reads the remaining data and reads the normal data again. ).
    At this time, the data to be temporarily stored among the data read from the CD kit 10 is stored in the RAM 40, and all programs used by the CPU 30 are stored in the ROM 50.
    On the other hand, the present invention is not limited to the above embodiment and can be variously modified within the scope without departing from the technical gist of the present invention, it can be applied to use in LD, LPD and the like.
    As described above, the present invention is a bad CD playback method, even if the CD state of the unspecified CD is abnormal due to the scratches or fingerprints, even if the state of the CD continues beyond the extremely bad place, even if the CD of any state There is an effect that can be played to the end.
