Description

광 디스크Optical disc

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제3도는 본 발명에 따른 광디스크를 도시한 사시도,3 is a perspective view showing an optical disk according to the present invention;

제4도는 본 발명에 따른 광디스크의 작동상태를 개략적으로 발췌 도시한 것으로서,4 schematically shows an operating state of the optical disk according to the present invention.

(가)는 광디스크의 A면이 하면에 위치한 경우의 단면도,(A) is a sectional view where the A side of the optical disc is located on the lower surface,

(나)는 광디스크의 A면이 상면에 위치한 경우의 단면도.(B) is sectional drawing when A side of optical disc is located on the upper surface.

Claims (2)

양면에 리드인영역과 리드아웃영역 및 정보수록영역이 각각 구분되어 있는 양면재생용 광디스크에 있어서, 상기 광디스크(20) 양면중 적어도 어느 한면의 리드아웃영역(23)에 그 광디스크(20)의 양면을 인식시키기 위한 인식수단이 구비된 것을 특징으로 하는 양면재생용 광디스크.An optical disc for double-sided reproduction in which a lead-in area, a lead-out area, and an information recording area are respectively divided on both sides, wherein the lead-out area 23 of at least one of the two sides of the optical disc 20 is on both sides of the optical disc 20. Recognizing means is provided for recognizing a double-sided playback optical disc characterized in that. 제1항에 있어서, 상기 인식수단이 환형의 광흡수층(26)으로 된 것을 특징으로 하는 양면재생용 광디스크.An optical disc for double-sided reproduction according to claim 1, wherein said recognition means is an annular light absorbing layer (26). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
