摘要： In one embodiment, an apparatus includes at least first and second modules, a mechanism for orienting the modules to control a transducer pitch presented to a tape, and a controller physically configured to determine a state of expansion of the tape based on a readback signal from the tape. Each of the modules have an array of transducers. The first and second modules are fixed relative to each other. The transducers of the first module are about aligned with the transducers of the second module in an intended direction of tape travel thereacross when longitudinal axes of the arrays are oriented at an angle greater than 0.2° relative to a line oriented perpendicular to the intended direction of tape travel. The controller is physically configured to control the mechanism for altering the angle of the modules away from the nominal angle based on the state of expansion of the tape.

摘要： For a Tunneling Magnetoresistive (TMR) element, an electrode is used as a magnetic shield or vice versa. This can pose a problem in that noise from a heater source or electromagnetic induction has a direct influence on the TMR element, namely, on a read signal. According to one embodiment of the present invention, however, a thin film head portion has an insulating film, a heater, an electromagnetic shield, a read element, and a write element laminated in this order from the side of a slider. Insulating films isolate the constituent elements above from each other, and a protection film covers the group mentioned above. The heater is a thin film resistive element made of NiCr or the like, and is disposed above the insulating film. The electromagnetic shield is a magnetic film made of permalloy or the like, and covers the heater. The read element comprises a lower shield and electrode, a TMR element, and an upper shield and electrode. The write element comprises a lower magnetic pole piece, an upper magnetic pole piece, and a coil formed therebetween. The thin film head portion is formed with a common terminal.

摘要： A manufacturing method for a magnetic head includes the steps of; forming a structure on a lower shield, the structure including a lower gap, a main magnetic pole and first and second side gaps; forming first and second side shields; forming an upper gap; and forming an upper shield. In the step of forming the structure, an initial lower gap layer is formed on the lower shield, the initial lower gap layer including a pre-lower-gap portion, and two to-be-removed portions that are located on opposite sides of the pre-lower-gap portion. Then, a protrusion including the main magnetic pole and the first and second side gaps is formed on the pre-lower-gap portion. With the top surface of the protrusion covered with a mask, the initial lower gap layer is etched in part to thereby form the lower gap.
