摘要： PROBLEM TO BE SOLVED: To realize an information recording medium capable of performing the high-density recording of a pitch smaller than that of a wavelength of light and to provide a method for recording and reading information. SOLUTION: In the information recording medium on which information is recorded by energy beams or magnetic fields such as a laser beam and an electron ray, and the method for recording and reading the information, a bubble which can move in the direction of a recording track without irradiation of at least a kind of energy beam such as an air bubble, a liquid bubble and a magnetic bubble, is created. The irradiation or the application of the energy beam or the magnetic field to a recording medium in which the size of a bubble becomes large by the irradiation of an energy beam or a magnetic field for reading, is performed while moving the position of the energy beam or the magnetic field on the recording medium. Recording is performed by producing or expanding bubbles and the bubbles are stored by reducing the size of the bubbles after the irradiation or application of the energy beam or the magnetic field. The presence and the position of the bubble are detected and read by expanding the bubble in the place where the irradiation or the application of the energy beam or the magnetic field for reading is performed.

摘要： PURPOSE:To identify the presence of the magnetic domain in a submicron size and to make a magneto optical recording in a high density compared to the conventional method by projecting to a medium the electron beam having higher space resolving power than that of a light as a reading means. CONSTITUTION:The spin of a secondary electron 6 jumping out of the medium by the projection of a primary electron is polarized by the magnetization of the medium, but the polarization degrees differ by the direction of the magnetization and the presence of a crescent magnetic domain, namely the presence of a record pit can be detected if a spin detector is arranged at the prescribed position. The crescent magnetic domain means 0.4mum bit period and 0.2mum magnetic domain width, a polarized spin is 0.2mum space resolving power at its space resolving power and the presence of the magnetic domain is discriminated thereby. The inner part of a vacuum chamber 8 is exhausted upto 5X10 Torr for a reading, for example, and a field emission type electron gun 5 is used at acceleration voltage 4kV and 3nA current value. The discrimination time as to whether a crescent record is made or not actually depends upon the sensibility and weight of the detector 7 detecting the polarization of the polarized spin 6 at high density.

摘要： PURPOSE:To attain recording with high density by using a magnetic field generating a signal magnetic domain recorded on a magnetic recording medium so as to detect a deflected electron beam thereby reproducing the information. CONSTITUTION:When the electron beam 3 radiated from an electron beam generator 2 passes the vicinity of the boundary between two recording pits magnetized in opposite direction on a magnetic recording medium 1, the leakage magnetic field 4 generated from the recording medium 1 is made nearly in parallel with the progressing direction of the electron beam at the passing location of the electron beam. Thus, the electron beam 3 is not subjected to the Lorentz force but goes straight forward and is made incident on a detector 5 to detect a target current (i) to detect recorded pits recorded on the recording medium 1. Since the electron beam 3 is formed into a thin beam as mum or below easily, it is possible to reproduce the recording pits whose track width is 1mum or below. Thus, the high density information is attained.

摘要： PURPOSE:To obtain a magnetic sensor small in size and high in reliability and capable of reading information recorded on a magnetic recording medium with high accuracy by utilizing effectively the principles of operation of a circulator. CONSTITUTION:A magnetic recording medium running section 16 in which a magnetic recording medium 15 directly contacts a Faraday rotation element 11 or runs with a very small gap to the element 11 is provided with a side opposite to the other side arranged with a magnet 14 of the Faraday rotation element 11. When a prescribed electromagnetic wave is inputted to an input waveguide 12 and a bias magnetic field of the magnet 14 is made constant at a prescribed strength, the prescribed electromagnetic wave is transmitted to an output waveguide 13 and outputted. When the magnetic recording medium 15 recorded magnetically is passed through the magnetic field, the synthesized magnetic field between the signal magnetic field and a bias magnetic field is activated to the Faraday rotation element 11 to control the rotation of the polarized plane to the electromagnetic wave. As a result, an output approximately proportional to the signal magnetic field appears in the output waveguide 13.
