NEAR-FIELD OPTICAL HEAD, AND INFORMATION RECORDING AND REPRODUCING DEVICE

摘要

A near-field optical head is provided with a near-field light emitting element that is set on a surface of a slider set opposite to a surface of a magnetic recording medium, has a plurality of side surfaces in contact with the opposite surface at a predetermined angle, and emits near-field light; at least one lower wiring arrangement formed on at least one of the side surfaces of the near-field light emitting element; a thin film-like magnetic pole disposed at a position to cover the lower wiring arrangement; at least one upper wiring arrangement disposed on a side reverse to the side where the lower wiring arrangement is disposed out of both sides of the magnetic pole; at least one side wiring arrangement to connect the lower and upper wiring arrangements; insulating layers to insulate the lower wiring arrangement, the magnetic pole and the upper wiring arrangement, respectively; and a coil wound around a circumference of the magnetic pole by alternatively connecting in series the lower wiring arrangement with the upper wiring arrangement through the side wiring arrangement.
