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。

Abstract: An optical information recording medium is composed of at least a phase-change type recording layer 4 provided on a substrate 1. The optical information recording medium is conducted to record and erase information by changing a phase of the phase-change type recording layer by irradiating light. The phase-change type recording layer is further composed of TiwGexSbyTez, wherein each of w, x, y and z is in atomic percent and satisfies following relations: 0.5nullwnull4.0, 3.4nullxnull14.5, 2.1nully/znull4.0 and wnullxnullynullznull100.

Abstract translation: 光信息记录介质至少由设置在基板1上的相变型记录层4构成。光信息记录介质通过照射相变型记录层的相位来进行记录和擦除信息 光。 相变型记录层还包括TiwGexSbyTez，其中w，x，y和z中的每一个都是原子百分比，并且满足以下关系：0.5 <= w <= 4.0,3.4 <= x <= 14.5,2.1 < = y / z <= 4.0，w + x + y + z = 100。
