A magnetic recording and playback apparatus of perpendicular recording type comprises a main pole having a magnetic axis which is normal to a recording surface of a magnetic record medium, an auxiliary magnetic pole disposed in surrounding relationship with the main pole with a small clearance from the lateral side thereof, a coil disposed on part of the auxiliary pole, and a yoke having its one end connected to the auxiliary pole and having its other end of a relatively large area disposed in opposite relationship with the recording surface of the record medium. The free end of the main pole is disposed in contact with the surface of the record medium while the yoke is disposed at a given distance from the surface of the record medium. During a recording operation, a current is passed through the coil in accordance with information to be recorded. Thereupon, a magnetic flux is concentrated in the free end of the main pole to cause an inversion of magnetization in that region of a magnetic layer of the record medium which is contacted by the main pole, thus recording the information. During a playback operation, the free end of the main pole picks up a magnetic flux which depends on the magnetization, representing the information, recorded in the magnetic layer of the record medium, producing a corresponding current flow through the coil. An output current from the coil is utilized for reproduction of the recorded information.

A method and apparatus for recording information on a magnetic recording medium with high density is provided. A heat spot of predetermined area is applied to the recording medium to raise the local temperature of the recording medium where the heat spot is applied above the Curie point of the recording medium. The heat spot is moved along the recording medium and a magnetic field is applied when a part of the recording medium heated by the heat spot is in the neighborhood of the Curie point in its cooling process, thereby recording information on the recording medium. In accordance with the present invention, an element or bit of information to be recorded on the recording medium is formed by a portion of the heat spot; thus, it relaxes recording conditions and allows to increase recording density.

摘要:
A magneto-optical recording method is capable of carrying out overwriting on a magneto-optical recording medium including a single perpendicular magnetic layer serving as a recording layer, by applying laser beams thereto, thereby controlling the formation and erasure of magnetic domains, in which a magnetic domain with a desired length can be formed or erased by the application of a plurality of laser beams during the formation and erasure of the magnetic domains.
摘要:
A game apparatus executes a game in which a player character is moved between different fields through a given traveling route according to an instruction input from a player. When the player character moves to a first area close to a door, a symbol “!” is displayed. When the character moves to a second area, a symbol set “!!” is displayed. In the second area, if unlocking conditions for the door are satisfied, a method of manipulation for opening the door is displayed. If the conditions are not satisfied, a method of manipulation for displaying a hint for opening the door is displayed. If the conditions for unlocking the door are satisfied, when the player performs the manipulation for opening the door, an action of the player character to open the door is displayed. Map data of the destination room is loaded into a temporary storage from a recording medium and then the player character moves to the opposite room through the door.
