摘要： In an apparatus for generating a magnetic field, first and second electromagnetic coils are linearly arranged on a yoke. The coils face one surface of an optical disk. An optical head is positioned above the other surface of the optical disk. A track address for denoting a track on the optical disk is picked up from the optical disk by the optical head and an information signal processor. A first and/or second energizing signal is generated from a switching circuit in accordance with the track address. Thus, one or both of coil drive circuits are driven in response to the energizing signals, energizing one or both of the coils, so that a predetermined magnetic field is applied to the optical disk from the selected coil or coils.

摘要： A reproduction apparatus for an optical magnetic disk having data recorded in a magneto-optical recording form and an address recorded in an optical recording form, includes a pickup for detecting P- and S-axis components of a linearly polarized laser beam reflected on an optical magnetic disk, an adder for adding the P- and S-axis components, and a subtracter for subtracting the S-axis component from the P-axis component. A reproduction signal processing circuit confines an output of the adder and that of the subtracter to produce a reproduction signal. A comparator converts the reproduction signal into a binary signal, the reproduction signal processing circuit including a circuit for identifying whether a reproduction signal is one of magneto-optical recording information or one of optical recording information. A variable gain amplifier amplifies the subtraction signal of the P- and S-axis components, at an amplification factor corresponding to a result of identification, in which the reproduction signal of optical recording information has a greater amplification factor than the amplification factor of the reproduction signal for magneto-optical recording information.
