摘要： A head unit for use in a helical scan magnetic tape drive comprises a substrate having a substrate surface (300) and multiple thin film magnetic elements (D1, D2) formed on the substrate. Each of the multiple thin film magnetic elements has an interactive component for transducing information with respect to magnetic tape. The interactive components of at least two elements are situated on different planes at respective different distances from the substrate surface. None of the multiple elements of the head unit are situated to traverse a same path on the magnetic tape. Moreover, all of the multiple elements of the head unit perform a same type of transducing operation.

摘要： A compound magnetic head having a recording and reproduction head unit (6A) in which a plurality of film heads are joined to each other so that head gaps (R/W-1, R/W-2...) are arranged at predetermined intervals in the widthwise direction of tracks (T1, T2...), and an erasing head unit (6B) in which a plurality of bulk heads, which correspond to the film heads, are joined to each other so that head gaps (E1, E2...) are arranged at predetermined intervals in the widthwise direction of the tracks (T1, T2), the recording and reproduction head unit (6A) and erasing head unit (6B) being joined to each other in the lengthwise direction of the tracks (T1, T2) so that the opposed head gaps (R/W-1), (E1); (R/W-2), (E2) therein are comparatively close to each other. A plurality of bulk heads (60A) may be used instead of the film heads. Change-over amplifier means (SW1-SW4, 77) may be added to the two magnetic heads so that a predetermined voltage dividing signal consisting of a reproduction signal from one magnetic signal differentially works even on a reproduction signal from the other magnetic head. In order to increase the level of a signal picked up by a head tip (6) provided on a base (7), step-up transformers (31, 32) may be set on the base (7). Also, a recording and reproduction change-over switch circuit (100), a recording amplifier (93) and a differential input amplifier (90), which consist of hybrid IC's, may be provided on the base (7).

摘要： This invention relates generally to composite magnetic heads and relates particularly to composite magnetic heads operating with respect to multitrack recorder carrier (32). The composite magnetic head is adapted to record and read records to and from a record carrier particularly suited to a multitrack record carrier (32) and more particularly suited to a multitrack magnetic tape. A composite magnetic head may be moved transversely with respect to the direction of movement of the record carrier so that head alignment with any one of the multitracks of the record carrier may be achieved. The record carrier (32) contacts the head assembly defining a scrub surface (22). A yoke (20) is provided supporting a ferrite core (10) containing an effective gap (26) which permits the head to be physically mounted with respect to the record carrier (32). The yoke (20) is constructed and mounted so that one surface of the yoke (20) is coplanar with the scrub surface (22) of the ferrite core (10) and which extends in both directions transversely to the motion of the record carrier (32) at least a distance equal to the width of the record carrier in each direction so that the record carrier may be evenly supported over the range of movement of the record carrier. A central open area of the yoke (20) is provided to allow for physical access to the coil windings (18, 30) of the ferrite core.

摘要： A composite magnetic core (10) is held by a slider (20) having two noses (25) for preventing the core (10) from falling. On the surfaces opposed to each other of the two noses (25), two protrusive contacting parts (26), with which contacted is the composite magnetic core inserted into a core slit (22) of the slider, are formed respectively. Each contacting part (26) extends in the direction of the height of each nose (25). Thereby, the slider can be so molded in one body that the distance between the two noses is adjusted more accurately in agreement with the thickness of the composite magnetic core. As a result, the composite magnetic core is prevented surely from falling, and can be aligned with the slider, accurately.
