摘要： A combined thin film magnetic head includes a first yoke type magnetic head (200a) and a second yoke type MR head (200b) a front gap (20a, 20b) is provided at a front end of the first yoke type MR head (200a), and a second yoke type MR head (200b) is provided behind the first yoke type MR head (200a). Consequently, the first yoke type MR head (200a) and the second yoke type MR head (200b) can be formed on the same substrate through the same process steps, and the number of manufacturing steps can be significantly reduced.

摘要： The device comprises a Wheatstone bridge with at least four magnetoresistive elements (1a, 1b, 1c, 1d) on a substrate (15), each magnetoresistive element comprising at least one sensitive portion (13) comprising successively a first ferromagnetic layer (19) having a magnetic easy axis (27) extending in a first direction, a non-magnetic layer (21) and a second ferromagnetic layer (23) having a magnetic easy axis (29) extending in a second direction that is different from the first direction. The sensitive portions (13) have mutually parallel sensitive directions that are parallel to a third direction (X). Each magnetoresistive element (1a, 1b, 1c, 1d) is associated with a current conductor (35a, 35b, 35c, 35d) provided in the immediate vicinity of that magnetoresistive element. The first direction (27) is canted through an acute angle with respect to the third direction (X), and the second direction (29) is canted in the opposite sense through an acute angle with respect to the third direction. Each one of the current conductors (35a, 35b, 35c, 35d) extends over at least a portion of its length in a fourth direction (Y) perpendicular to the third direction (X).

摘要： A read head with two read sensors enables reading of a magnetically recorded medium of increased areal densities such as would be provided by two-dimensional magnetic recording. The two sensors, which may be formed in separate depositions, are arranged vertically relative to each other as top and bottom sensors, with a downtrack displacement between them that is less than 900 A and a crosstrack displacement that is less than 600 A. Their separate free layers are connected by four or three conducting leads and require no junctions for their connections. In one embodiment each sensor has separate top and bottom shields and leads. In another embodiment, there is a common shield and lead between the two sensors, but a separate top shield/lead for the top sensor and bottom shield/lead for the bottom sensor.
