    Abstract: A magnetic head adjusting mechanism operable to adjust the position of magnetic heads (2, 3) with respect to the direction of the run of a web (1) of a magnetic recording medium in dependently of the adjustments of the head gap angle, the heights of the heads and other adjustment items. The mechanism includes a head base plate (19) carrying the magnetic heads (2, 3) and formed with a shaft bore in which is fitted a support shaft (14) mounted on a chassis (22). The head base plate (19) is resiliently biased about the axis of the support shaft (14). The rotation of the head base plate (19) about the support shaft (14) is limited by a tapered adjusting member formed by a tapered nut (17) having a conical outer surface in contact with the head base plate (19) and a screw shaft (21) in threadable engagement with the tapered nut. The screw shaft (21) is mounted on and extends from the chassis (22) to support the tapered nut such that the generating line of the conical surface of the nut, which includes the point of contact of the nut (17) with the head base plate (19), is substantially parallel to the axis of the support shaft (14).

    Abstract: A magnetic head (20) of a magnetic head device has a head guide (21) which has a groove (23) in its side surface. A support table (33) has a recess (33a) in which the lower portion of the head guide is fitted. Screws (41, 42) are screwed upward from the bottom of the support table and extend into the recess. The head guide is supported on the screws. An elastic plate (31) which has central and radially extending perforations (31a, 31b) at its center portion is mounted on the upper surface of the support table. A portion of the elastic member which defines the central perforation (31a) is fitted in the groove of the head guide. The head guide is then biased toward the screws. When the screws are turned, the level and azimuth of the magnetic head can be adjusted. A pressure pad (50) is also adjusted by other screws (64) to be set at a selected position relative to the magnetic head and at a selected tilt angle with respect to the magnetic head.

    Abstract: A magnetic head arm assembly comprises a lightweight, low inertia frustoconical arm (10) to which a magnetic head (12) is mounted at one end. The other end of the head arm is coupled to an end of a rotatable shaft (14), by which the arm can be pivoted. An electrical coil (16) which is disposed within a magnetic field supplied by permanent magnets (20,22) is fastened to the other end of the shaft (14). The pivotable magnetic head arm assembly may be vertically adjusted to control flying height and angularly adjusted relative to the surface of a magnetic diskto correct for azimuth variations.

    Abstract: A method of aligning a multiple transducer magnetic head with respect to a magnetic recording tape. Values related to the offset of each transducer from a reference location are determined, using reference signals on the tape. From these values, the amount of compensation required to accurately position any particular transducer with respect to any track can be calculated. By a preferred selection of the reference for one such offset value, and by taking known design of the head into account, simplified processing of the values is possible.

    Abstract: The invention relates to a method for positioning a magnetic head on the portion of a track where the level of the recorded signal is maximum. The method is characterized in that the position of maximum signal level is obtained by assimilating the curve representing the mean signal level read versus the position of the magnetic head on the track width to a simple symmetrical geometrical form of which is determined an equation of portions of straight lines defining it. Application to the positioning on high density magnetic media.

    Abstract: A mechanism for adjusting the position of a magnetic head for a magnetic tape recorder/reproducer which enables optimum adjustment of the position at which the head gap of a magnetic head contacts the magnetic track provided on a magnetic tape or sheet. A magnetic head mounting plate (2) to which a magnetic head (1) is affixed is disposed on a head gap adjusting plate (9) rotatably supported on a substrate (4), the mounting plate (2) being supported by a pair of supporting shafts (14, 15) implanted in the adjusting plate (9) along the central longitudinal axis of the magnetic head (1). The mounting plate (2) is supported by a pair of posts (16, 19) implanted in the adjusting plate and is rockably movable about a line connecting the pair of the supporting shafts. The azimuth adjustment of the head gap (1a) is conducted with respect to the magnetic track (8a) by turning a nut (17 or 20), and the contacting angle adjustment is conducted by turning an eccentric shaft (12).
