摘要： A non-magnetic intermediate layer is provided between a reproductive layer and a recording layer. The reproductive layer is composed of a first reproductive layer and a second reproductive layer. When the first reproductive layer has a temperature that is higher than a first critical temperature, its stable magnetic domain width becomes smaller than a recording magnetic domain width so that the magnetization is reversed. When the second reproductive layer has a temperature that is higher than a second critical temperature, its stable magnetic domain width becomes larger than the recording magnetic domain width so that the reversed magnetic domain is collapsed. The first critical temperature is lower than the second critical temperature. A reproductive output having abrupt rising and falling can be obtained by the generation and the collapse of the reverse magnetic domain on the reproductive layer. For this reason, higher density recording required for larger capacity can be achieved.

摘要： A magneto-optical recording medium has (1) a first magnetic layer made of a magnetic material which is changed into a vertical magnetization film in response to a temperature rise while is an in-plane magnetization film at a room temperature; (2) a second magnetic layer made of a vertical magnetization film; and (3) a third magnetic layer made of a vertical magnetic film having a higher Curie temperature than that of the second magnetic layer; and (4) a base substrate on which the first, second, and third magnetic layers are luminated in this order. With the arrangement, the optically modulated overwriting can be carried out with respect to the second magnetic layer and it is not necessary to complete the magnetization direction to one direction for each optically modulated overwriting. Moreover, it is possible to reproduce through the first magnetic layer the information which is recorded on a smaller portion than a light beam spot.

摘要： A magneto-optical recording method for rewriting of information including the steps of projecting a light beam, whose intensity varies in response to information to be recorded, onto a magnetic thin film with perpendicular magnetization while an external magnetic field of a constant intensity is being applied thereto; and arranging the magnetization direction of an area irradiated with the light beam of the magnetic thin film with perpendicular magnetization in the direction of the external magnetic field when projecting the light beam of high intensity, while arranging it in the direction of demagnetizing field, opposite to the direction of the external magnetic field generated by magnetization in the vicinity of the irradiated area when projecting the light beam of low intensity, and a magneto-optical memory element provided with a base whereon the magnetic thin film with perpendicular magnetization and an in-plane magnetization film are formed. With the above arrangement, an overwriting operation can be carried out through light intensity modulation without requiring an initialization magnet.

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.
