Abstract: A transducer for writing data on a magnetic carrier includes a magnetic circuit having a writing pole piece (PPI.sub.2), realized in thin magnetic layers of anisotropic magnetic material. A conductor (CMPI) for controlling the writing is coupled magnetically with the pole piece and acts upon the pole piece for writing a datum by reversing the magnetization. A second control is magnetically coupled with the pole piece (PPI.sub.2), but does not act upon the pole piece except in the case of non-writing by diminishing the effective action of the conductor control.

The platform is supported from a carrier arm adapted to position the platform over the data carrier which may be a multi-track disc. The magnetic transducer is supported in the lower face of the main body of the platform. The lower face includes a plurality of skids and one or more grooves which receive a rigid strut for suspending the platform over the carrier. The strut is secured in the groove (s) with the plane of the strut passing through the centers of gravity of the platform. The strut may be secured to a frame surrounding the platform which in turn may be secured to a further concentric frame also surrounding the platform.

Abstract: A magnetoresistant transducer for reading data present on the tracks of a multitrack magnetic carrier, comprises at least one magnetoresistant element perpendicular to the direction of travel of the data, and first and second magnetic screening means situated at either side of the element.The magnetoresistant transducer comprises deflecting means for deflecting the magnetic field generated by the current flowing through the element. The deflecting means are situated between the latter and the first and second screening means to intercept and deflect the magnetic field lines transmitted by the data items on the track. The deflecting means includes a plurality of mutually parallel thin magnetic blades separated from each other by thin non-magnetic laminations the thickness of which is such that the magnetic coupling between two adjacent laminations is weak. The laminations and magnetoresistances are of anisotropic material and have their axes of easy and difficult magnetization parallel to each other.

Abstract: A substrate for perpendicular anisotropic magnetic recording comprises a nonmagnetic substrate (SUBSI) on which a thin metal magnetic medium (CMI) having a negative magnetostrictive effect is deposited. The direction of easy magnetization of the medium is perpendicular to the surface. In order to minimize the magnetostrictive effect in the metal magnetic medium, the medium comprises a stack of alternate thin magnetic and nonmagnetic layers (CI.sub.1 -CI.sub.n, ISO.sub.1 -ISO.sub.n-1), the nonmagnetic layers (ISO.sub.1 -ISO.sub.n-1) being sufficiently flexible so as to dampen the effect of the strains in the magnetic layers and enable strong magnetic coupling between them. The thickness of the nonmagnetic layers is between 150 and 250 angstroms, while the thickness of the magnetic layers is between 700 and 2000 angstroms. The stack may include as many as 10 or more magnetic layers of a chrome/cobalt alloy. The nonmagnetic layers may be SiO, SiO.sub.2 and mixtures thereof. The invention is applicable to magnetic recording disks.

Abstract: A magnetic transducer for reading magnetic information from a magnetic support such as a disc or tape which moves before it, comprises a magnetic circuit formed of two thin layer polar pieces having a gap at one end and means coupled magnetically to the circuit for transformation of magnetic flux loss of information into an electric signal. The pole pieces comprise at the level of the gap a central part bounded by two lateral parts spaced such that the magnetic coupling between the central parts is very much less than the magnetic coupling between the corresponding lateral parts of the pieces. The gap disposed between the central parts is larger than the gap of the lateral parts. There is a substantial reduction in Barkhausen noise and parasitic edge effects over conventional transducer constructions which is obtained by making the thickness of the pole pieces of the transducer substantially greater in the area of the geometric path Lpm than at the lateral portions beyond Lpm.
