摘要： An optical read/write apparatus causes a read/write light beam from illuminating means to strike only one side of an optical storage medium including stacked data storage layers each of which is readable/writeable separately from the other layers. In this case, the optical read/write apparatus operates so that data is read/written from/into a second data storage layer after fully recording a recordable area of a first data storage layer. Thus, light can be shone with uniform intensity across the substantially entire recordable area of the second data storage layer without using a complex read/write system even under such conditions that the transmittance to light of the first data storage layer in the recordable area may vary depending on whether any data is recorded in the recordable area.

摘要翻译： 光学读/写装置使得来自照明装置的读/写光束仅对包括堆叠的数据存储层的光存储介质的一侧进行打印，每个存储层与其它层分开地可读/写。 在这种情况下，光学读/写装置的操作使得在完全记录第一数据存储层的可记录区域之后，数据从/向第二数据存储层进行读/写。 因此，即使在可记录区域中的第一数据存储层的透光率可以变化的条件下，也可以在第二数据存储层的大致整个可记录区域上照射光，而不使用复杂的读/写系统 取决于任何数据是否记录在可记录区域。

摘要： A reproducing layer, an intermediate layer, and a recording layer are successively stacked. The reproducing layer is made of a perpendicularly magnetized film whose domain wall coercivity is relatively smaller and whose domain wall mobility is relatively larger as compared with the recording layer around a reproducing temperature. When the reproducing layer, the intermediate layer, and the recording layer have Curie temperatures of Tc1, Tc2, and Tc3, Tc1, Tc2, and Tc3 satisfy a relationship of Tc2

摘要： A squeeze pump has an elastic tube disposed between an inlet and an outlet of a cylindrical drum and extends along an inner peripheral surface of the drum. A pair of pressing rollers spaced by 180 degrees are arranged to press the tube. The tube is deformed into a flat shape with two bent portions to transfer a slurry within the tube. The tube has a large diameter in the inlet and a small diameter in the outlet. Each pressing roller has a large diameter formed at the middle and a small diameter at both ends. A support member extends along the inner peripheral surface of drum to support at least one of the bent portions of tube when the tube is pressed by the pressing roller.
