    摘要： A magnetic head assembly for recording and playing back information on a recording medium in a vertically magnetized mode. Main and auxiliary heads are provided opposite one another with the recording medium passing therebetween. The main head includes a core of material exhibiting a magnetoresistance effect to which core are attached leads which carry the output play back signal. The auxiliary head has a magnetic core around which is wrapped a winding carrying the recording current. The recorded information patterns have their primary magnetic field components perpendicular to the surface of the recording medium.

    摘要： A method of producing a magnetic recording layer on a support comprising simultaneously depositing a ferromagnetic material and a polymer on a support using a vapor deposition technique such as vacuum deposition, sputtering, etc., thereby to produce thereon a magnetic recording layer of a composite film of the ferromagnetic material and the polymer. A further embodiment for producing a magnetic recording layer comprises simultaneously depositing a ferromagnetic material and a monomer or oligomer on the support using a vapor deposition technique, polymerizing the deposited layer, e.g., using a polymerization catalyst or by applying ionizing or electromagnetic rays thereto, to form a composite film of the ferromagnetic material and the polymer. The magnetic recording layer thus obtained in either embodiment can be used for high density recording.
