Abstract:
A recording medium has a first area storing an audio title set. The audio title set contains a plurality of audio objects including a first audio object and a second audio object. The first audio object consists of first packs having audio data. The second audio object includes second packs having audio data and a third pack having real-time information related to the audio data in the second packs. The recording medium has a second area storing a still-picture set. The still-picture set includes a fourth pack having still-picture data related to the audio data in the first packs and the audio data in the second packs.
Abstract:
An optical information recording medium 10 is composed of at least a reflective layer 2, a first protective layer 3, a phase-change type optical recording layer 4 and a second protective layer 5 being sequentially laminated on a substrate 1. The optical information recording medium 10 is conducted to record information by changing a phase of the phase-change type optical recording layer 4 by irradiating light from the second protective layer 5 side. The phase-change type optical recording layer 4 further contains at least Ti, In, Ge, Sb and Te. When each content amount of the Ti, In, Ge, Sb and Te is defined as v, w, x, y and z in atomic percent respectively, each content amount of v, w, x, y and z in atomic percent satisfies following relations: 0.3nullvnull4, 0.3nullwnull3, 3.4nullxnull14.5, 2.1nully/znull4 and vnullwnullxnullynullznull100.
Abstract translation:光信息记录介质10至少由反射层2,第一保护层3,相变型光记录层4和第二保护层5构成,顺序层叠在基板1上。光信息记录介质 通过照射来自第二保护层5侧的光来改变相变型光学记录层4的相位来进行记录信息。 相变型光学记录层4至少还含有Ti,In,Ge,Sb和Te。 当Ti,In,Ge,Sb和Te的每个含量分别以原子百分比定义为v,w,x,y和z时,原子百分数的v,w,x,y和z的每个含量满足以下 关系:0.3 <= v <= 4,0.3 <= w <= 3,3.4 <= x <= 14.5,2.1 <= y / z <= 4和v + w + x + y + z <= 100。
