The information recording medium also includes a magnetic recording layer which is provided on a back surface of the optical recording portion. The magnetic recording layer includes a magnetic layer, a concealing layer, a print layer, and a print protective layer. The concealing layer includes a metal film.

COMPATIBLE DISK PLAYER

The present invention relates to a compatible disk player, which is capable of playing compact disk CD or laser disk LD. More specifically, the disk player of the present invention reduces the delay time between loading and actually playing a disk. It includes a manual switch on the disk player, from which a person may select the type of disk to play, thereby decreasing the time needed to determine which type of disk is entered. If the CD mode is selected or the last disk to be played was a CD, the player pick-up is placed in the initial playing position of the CD before a disk is entered. After entering a disk, if it determines that an LD is loaded or the CD mode is cancelled (by the manual switch) the pick-up is moved to a ready position for the LD. By including a manual switch and circuitry which assumes the next disk type is the same as the last, the present invention reduces the time needed to determine which type of disk is loaded.

Disc discrimination method for CD and DVD disc players

본 발명은 씨디 및 티브이디 겸용 디스크 플레이어에서 디스크 판별방법에 관한 것으로, 종래의 겸용 디스크 플레이어는 씨디용 레이져다이오드가 광픽업에서 설정되어 있어 씨디용 디스크를 장착시에는 사용자가 임의의 조작이 필요 없으나 디브이디용 디스크를 재생하고자 하면 트래이에 디브이디용 디스크를 장착하고 임의의 변환키를 눌러주어 레이저 다이오드의 설정상태를 변환시켜 주어야하므로 그 조작상 번거로운 문제점이 있었다. The present invention relates to a disc discrimination method in a CD and TV combined disc player. In the conventional combined disc player, since the CD laser diode is set in the optical pickup, the user does not need any operation when the CD disc is mounted. In order to play the disc for DVD, there is a troublesome operation because it is necessary to mount the disc for DVD in the tray and press an arbitrary conversion key to change the setting state of the laser diode. 이에 본 발명은 듀얼 포커스를 위해 파장이 다른 두 개의 레이저다이오드가 설치된 씨디와 디브이디의 겸용 디스플레이어에 있어 디스크가 로딩됨에 따라 트랙킹 서보를 강제로 구동하여 검출된 알에프 패턴을 통해 로딩된 디스크에 해당하는 레이져 다이오드가 픽업부에서 자동적으로 변환되도록 하여 사용자의 조작에 따른 편의성을 증대하는 효과가 있다. Accordingly, the present invention corresponds to a disc loaded through an RF pattern detected by forcibly driving the tracking servo as the disc is loaded in the combined display of the CD and the DVD having two laser diodes having different wavelengths for dual focus. The laser diode is automatically converted in the pickup unit, thereby increasing the convenience according to the user's operation.
