    摘要: A highly accurate rotation angle detection device is realized by correcting a detecting position error caused by a machining error such as deterioration of roundness of an internal diameter of a stator. The rotation angle detection device is provided with a stator (12), which is provided with an exciting winding of one phase and two-phase output windings, and a rotor (13) having salient poles, in which the stator (12) has a plurality of teeth (11), the two-phase output windings are wound around the plurality of teeth, and the plurality of teeth include teeth for which the number of turns of the output windings is N and at least one of teeth for which the number of turns of the output windings is N±m (it is assumed that N and m are positive integers and N>m) and teeth for which the number of turns is m.

    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.
