摘要： A track on the disk is divided into plural concentric zones on the radial position thereof. During recording, the angular velocity varies according to the zones accessed for recording, and the disk is driven at a rotational velocity whereby the angular velocity is constant within any single zone but decreases as the radial position of the zone of the accessed track approaches the outside circumference of the disk. During reproducing, the disk is driven at a rotational velocity whereby the angular velocity is constant in all zones. The range of change in the relative linear velocity of the head to the track is thus smaller and the change in the recording conditions is less during recording. During reproducing, there is no delay time required for rotational control of the disk, and the desired track can be more quickly accessed.

摘要： A method for performing a high quality recording of information signals on an optical disk utilizes reversible structural changes between crystalline and amorphous states of a chalcogenide glass film or the like and two circular or nearly circular laser spots closely arranged along a recording track of optical disk. The preceding spot, which emits a continuous mode or high-frequency mode by far exceeding the recording frequency, operates cancel the past history in the irradiated portion by melting the recording film. The succeeding spot, which is modulated between the power levels for amorphizing and crystallizing according to the recorded information, operates to record new information signals on the track just after erased by the preceding laser spot.

摘要： A reversible optical information recording medium which permits recording, reproducing, erasing and rewriting at high speeds by means of laser beams. The reversible optical information recording medium has a recording thin film which is essentially constituted by Te-Au-O, and Ge or Se. In the system which employs Ge, the recording thin film is formed by addition of at least one selected from a group consisting of Sn, In, Bi and Sb, such as to reduce the Au content in the film composition. On the other hand, in the system which employs Se, a further improvement in the stability of the recorded signal is achievable by the addition of Ge, and an improvement in the recording/erasing sensitivities, particularly erasing sensitivity, can be enhanced by addition of at least one element selected from a group consisting of Sn, In, Bi and Sb. The recording/erasing mechanism in the reversible optical information recording medium of the invention mainly relies upon a change in the optical characteristic which in turn is caused mainly by a reversible phase change of Te. The phase change in the recording medium of the invention can be effected by a laser beam of an extremely low light power density and short irradiation time as compared with that required by the conventional optical information recording medium. This in turn permits much higher speed of recording and erasing of information over the conventional optical information recording medium.
摘要翻译：一种可逆光信息记录介质，其允许通过激光束以高速记录，再现，擦除和重写。可逆光信息记录介质具有基本上由Te-Au-O和Ge或Se构成的记录薄膜。在采用Ge的系统中，通过添加选自由Sn，In，Bi和Sb组成的组中的至少一种来形成记录薄膜，以减少膜组成中的Au含量。另一方面，在采用Se的系统中，通过添加Ge可以实现记录信号的稳定性的进一步提高，并且通过添加Ge可以提高记录/擦除灵敏度的提高，特别是擦除灵敏度选自由Sn，In，Bi和Sb组成的组中的至少一种元素。本发明的可逆光信息记录介质中的记录/擦除机制主要依赖于光学特性的变化，其特征在于主要由Te的可逆相变引起。本发明的记录介质的相位变化可以通过与传统的光学信息记录介质所需的相比，具有极低的光功率密度和短的照射时间的激光束来实现。这又允许在常规光学信息记录介质上记录和擦除信息的速度更高。
