Abstract
A method is presented for fabrication of a tape medium read head having a unitary formation of multiple elements for reading multi-track data from a magnetic tape. The method includes providing a continuous substrate layer, and forming a sensor material layer on the continuous substrate layer. Photoresist material is deposited on the sensor material layer, and is patterned to form masks which provide protected areas and exposed areas of the sensor material layer. Exposed areas of the sensor material layer are shaped to form sensors from the protected areas of the sensor material layer. Electrical lead materials are deposited between and adjacent to the sensors, and the masks are removed.
