摘要： An optical disk adapted to resist moisture absorption, warping and static charge is disclosed. The disk includes an SiO.sub.2 film coating over at least a portion of a disk substrate. Additionally, an optical disk having a magnetic film protected by a fluorocarbon polymer is disclosed. Either of such disks can be used individually or, alternatively, they can be used in a laminated structure having two disks laminated in a face-to-face relationship. The laminated structure can be covered with SiO.sub.2 film.

摘要： A magnetic thin film memory is provided including a plurality of magnetic thin film memory elements each adapted to record information on the basis of the direction of magnetization of a magnetic thin film thereof, the magnetic thin film memory elements being each composed of at least the magnetic thin film and a switching element. With such a constitution the magnetic thin film memory can be reduced in size while a sufficiently large signal can be obtained with a substantially improved SN ratio. A method for recording and reproduction information using the magnetic thin film memory is also provided. In another aspect, the present invention provides a magnetic thin film memory element including at least two kinds of magnetic layer, and a nonmagnetic layer which is interposed between the magnetic layers wherein the two kinds of magnetic layers are stacked so as to be coupled to each other by an exchange interaction through the nonmagnetic layer.
