<p>In making a magnetic transducer head with both read and write transducers a problem occurs as the transducers must be accurately aligned but are separated by an insulating layer. A method of making a read/write transducer head is disclosed which has separate read (16) and write (18) transducers comprises the steps of depositing a sequence of layers (32R, 34R, 20R, 40R, 38R) upon a substrate (10) to form read transducer (16); depositing a transparent insulating layer (44) with surface L upon read transducer (16) and lapping the layer flat to surface (S); depositing a sequence of layers (32W, 34W, 20W, 40W, 38W) upon insulating layer (44, S) to form write transducer (18), using optical alignment via transparent layer (44) to align the write transducer (18) relative to the read transducer (16); and finally depositing a protective insulating layer (46,L2) upon the write transducer (18). The substrate (10) may be formed as a slide with an air bearing surface for flying relative to a rotary magnetic disk.</p> |
