摘要： A recording head for a magnetic printer utilizes a so-called magnetography, in which a magnetic latent image formed on a magnetic recording medium is developed and actualized by a magnetic toner and which image is transferred and fixed on a sheet of recording paper to provide a hard copy. The recording head for a magnetic printer includes a first thermal head member, second thermal head member juxtaposed with the first thermal head member with a space therebetween, and a magnetic head member arranged on the first and the second thermal head members. A magnetic gap of the magnetic head member extends immediately above the space between the first and the second thermal head members linearly in the same direction. By this structure, a recording head for a magnetic printer which has simple structure and allows formation of a magnetic latent image having clear boundary between opposite magnetic polarities on a magnetic recording medium, is provided.

摘要： A magnetic storage device and a manufacturing method thereof, the magnetic storage device having grooves formed on a substrate, each of the grooves having a magnetic film formed therein. Since the magnetic head does not contact directly with the magnetic film, reliability of the magnetic disk increases. Moreover, the reproduced output of the magnetic head increases since the space between the magnetic head and the magnetic disk can be reduced. Accordingly, high-density recording becomes possible.

摘要： A magnetic recording medium, which includes a substrate and an amorphous magnetic layer, made of an amorphous magnetic material, for magnetic recording of data, is provided with an underlayer between the substrate and the amorphous magnetic layer, the underlayer being made of amorphous metal element, and having a mean thickness of 10 nm or less. In this manner, movement of magnetic domain walls of the amorphous magnetic layer is effectively limited by minute irregularities on a surface of the underlayer. This realizes a stable formation of a minute recording mark. This realizes recording having a sufficient signal quality, even when the high-density recording is performed by forming such a minute recording mark that a shortest length of the recording mark is less than 100 nm. Moreover, this allows the magnetic recording medium to have a simplified layer structure. Further, a magnetic recording apparatus magnetically records data onto a magnetic recording medium having the above arrangement, by heating a portion of the magnetic layer by radiating a light beam locally, and by applying a magnetic field on at least part of the portion of the magnetic layer on which the light beam is radiated. This provides a magnetic recording apparatus for high-density recording.

摘要： An optical device and a recording medium are provided with a recording layer for recording information by radiation of light, and a mask layer which is formed closely to the recording layer, reduces its transmittance of light due to light or heat, and transmits light to the recording layer by using a near-field effect. An optical reproducing and recording method includes the steps of: emitting a laser beam onto the mask layer, generating a near field around an area of the mask layer that has transmittance being reduced by the laser beam, and reproducing or recording optical information in the recording layer by interaction between the near field and the recording layer. With this method, it is possible to provide the optical device, recording medium, and optical reproducing and recording method that can realize a high S/N ratio upon reproducing and recording and that can readily form a recording mark.
