1,039,697. Magnetic structures. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 8, 1965 [June 25, 1964], No. 24138/65. Heading H1H. [Also in Division G5] A magnetic recording and playback head is made by assembling ferrite sheets 43 (Fig. 5). One sheet near the middle has a layer of platinum or palladium deposited on it at one edge and most or all of the sheets have two strips of conducting metal deposited (in a protective atmosphere if necessary) near the opposite edge. The assembly is heated and pressed to bond the layers together and cut at right-angles to the metal strips to form slices which are then shaped as in Fig. 8. Finally the slice is sintered, and printed conductors 91 are deposited to form with the conducting layers a winding around the completed head. |
