  • Patent number: 7174087
    Abstract: An equalizing circuit is provided for a playback apparatus not requiring tracking control. A playback signal is supplied to a plurality of unit delay devices which are connected in series, and the signals at the input ends and the output ends are supplied to weighting devices, respectively. Furthermore, the playback signal is supplied to a computation circuit, whereby weighting coefficients are determined. Weighting is performed on the signals from unit delay devices, and these signals are added together by an adder so that the equalization of the playback signal is performed, and the signal is extracted from an output terminal. Simultaneously, in the computation circuit, when the envelope value of the playback signal is within a range the phase lock for the playback signal is used so that the calculation of the weighting coefficients is done, and the coefficients of the weighting devices are changed.

  • Patent number: 6534203
    Abstract: A magnetic recording medium includes an anti-ferromagnetic layer 2 layered on at least one of the opposite major surfaces in a direction along the thickness of a ferromagnetic recording layer 3. It is possible for magnetization in the vicinity of a surface of an anti-ferromagnetic layer 2 facing a ferromagnetic recording layer 3 to be rotated simultaneously with rotation of magnetization of the ferromagnetic recording layer 3. It is also possible for the intensity of exchange coupling between the two layers to be larger than the total magnetic anisotropy of the anti-ferromagnetic layer 2. It is similarly possible for the intensity of the exchange coupling between the two layers to be smaller than the total magnetic anisotropy of the anti-ferromagnetic layer 2 and larger than the magnetic domain energy of the anti-ferromagnetic layer 2.

  • Patent number: 6449133
    Abstract: A magnetoresistance film has an ordered antiferromagnetic layer (1), a fixed magnetic structure portion (2) joined thereto, a non-magnetic conductive layer (3), and a free magnetic layer portion (4) having at least one magnetic layer, the fixed magnetic structure portion (2) having provided therein an amorphous magnetic layer (5). The magnetoresistance film is thereby constructed such that the amorphous magnetic layer (5) and the non-magnetic conductive layer (3) are joined to each other with a crystalline ferromagnetic intermediate layer (61) existing in between. Thereby, the fixed magnetic structure portion of a spin valve construction has therein the amorphous magnetic layer to thereby achieve the enhancement of the magneto-resistance change rate and the improvement of the heat resistance of the resulting magnetoresistance film.
