Unitary magnetic trasducer and suspension structure for longitudinal operation

摘要

A unitary magnetic transducer and suspension structure for longitudinal recording which can be used for contact recording and flying above the media. The transducer includes a horizontal first pole piece (62) and a horizontal (72) and vertical (94) sectioned second pole piece (96). The magnetic gap (92) is formed between the first pole piece (62) and the vertical section (94) of the second pole piece (96). The suspension layers are formed mainly from the insulation layer (66) that separate the first horizontal pole piece and the horizontal section of the second pole piece, and an insulation layer (82) that covers and protects the transducer layers. The layers of the unitary structure head are deposited on a wafer (50) in a row (52) and column (54) configuration. A release layer (60) is deposited on the substrate first and then the individual thin film layers of the transducer are deposited. A horizontal first pole piece (62) is formed. A horizontal section of a second pole piece (72) is formed and activated by a conductor coil (68/76) wound around the horizontal section. The backgap is displaced horizontally from the poletips. The wafer is then divided into rows (52). The vertical section (94) of the second pole piece (96) is formed on the end of the row in contact with its horizontal section. The substrate (50) is removed by attacking the release layers.
