发明名称 METHOD FOR PRODUCING A MAGNETIC RECORDING/READING HEAD AND APPLICATION IN A MATRIX HEAD
摘要 <p>The invention concerns a method for producing a layered magnetic head, at a substrate (1) surface comprising a magnetic material layer (M1), and, on said layer, at least two magnetic pins (P1 and P2) and at least one magnetic conductor forming a magnetic field coil for one of the magnetic pins. Said method consists in providing an encapsulating material layer (3), then producing on the encapsulating layer (3) a first mask (4) leaving clear on the encapsulating layer (4) a surface corresponding to the shape of two magnetic poles to be produced and a second mask (4) leaving clear a surface corresponding to the shape of a first magnetic pole to be produced; then etching the encapsulating layer (3) in the surface left clear by the two masks and up to at least one magnetic pin; then depositing a first magnetic material layer (6) on the whole resulting assembly; then attacking the second mask and etching the encapsulating layer (3) in the surface left clear by the first mask and by the first magnetic material layer; finally depositing on the whole assembly a non-magnetic material layer (7) then a second magnetic material layer (8), and polishing until the first magnetic material layer is reached. The invention is useful for producing magnetic recording/reading heads.</p>
