摘要： A magneto-optical recording medium made of a rare-earth-transition metal amorphous film provides a compensation temperature Tcomp of 50.degree.-200.degree. C. or 0.degree. C. or less. This compensation temperature decreases a saturation magnetization Ms during recording, thereby preventing the provision of inverted magnetic domains at the centers of recording domains resulting from the demagnetizing field generated by the strength distribution of laser light, and so improving a carrier-to-noise ratio during reading. In the case of using a Tb-Fe-Co system amorphous film, Tcomp of 50.degree.-200.degree. C. may be give by the composition comprising Tb of 24-30 atomic %, Co of 7-20 atomic % and Fe of the rest, and Tcomp of 0.degree. C. or less may be given by the composition comprising Tb of 18-21.5 atomic %, Co of 8-10 atomic % and Fe of the rest.
摘要翻译：由稀土 - 过渡金属非晶膜制成的磁光记录介质的补偿温度Tcomp为50〜200℃或0℃以下。该补偿温度在记录期间降低饱和磁化强度Ms，从而防止在由激光的强度分布产生的消磁场产生的记录域的中心处提供反向磁畴，并且因此提高了载波噪声比读。在使用Tb-Fe-Co系非晶膜的情况下，可以通过包含Tb为24〜30原子％，Co为7〜20原子％的Tb的组成和50〜200℃的Fe 可以由包含18-21.5原子％的Tb，8-10原子％的Co和其余的Fe的组合物给出0℃或更低的Tcomp。

摘要： A highly density magnetic bubble memory device has bubble propagation paths having different pattern periods. The distance between a propagation path having shorter period and a magnetic film for holding magnetic bubbles is made smaller than that between propagation path having longer period and the magnetic film. An insulating layer formed between the propagation path and the magnetic film through another insulating layer has a declining slope having an angle of 60.degree. or less, thereby ensuring steady propagation of the magnetic bubbles along the propagation path.

摘要： A field access magnetic bubble memory device including a memory chip applied with an in-plane magnetic field at need is disclosed. At a transient stop operation of the device before its interrupted state, an in-plane field is removed after it has been held for a predetermined period following the cessation of rotation thereof. The in-plane field may be increased upon the cessation of rotation thereof. At a transient start operation of the device after the interrupted state, an in-plane field having no rotation and the same direction as at the transient stop operation is applied for a predetermined period before the initiation of rotation thereof. The applied in-plane field may be increased upon the initiation of rotation thereof.
