摘要： PURPOSE:To press uniformly a magnetic head onto a magnetic recording medium, to prevent deterioration of a characteristic such as output fluctuation and to prevent damage to the magnetic recording medium by supporting a pressing means via a screw member and changing the screwed amount of the screw member so as to adjust the pressing force of the pressing means in a head device recording and reproducing the recording medium while clipping the recording medium from both sides. CONSTITUTION:One end of a spring 12 pressing magnetic heads 2, 5 onto the magnetic recording medium 1 is fixed to a spring fixing section 10 provided to a carriage 4 and the other end is fixed to a notch 16a of a pressing spring fixing member 16 provided with a screw part 17. The fixing member 16 is screwed into a screw hole 15 provided to an arm 14 and then the magnetic head device 19 is constituted. Through the constitution above, the tensile strength of the pressing spring 12 is adjusted by changing the screwed amount to the screw hole 15 of the fixing member 16. That is, the tensile force of the spring 12 is adjusted by the screw hole 15 provided to the arm 14 and a pitch 18 of the screw 17 formed to the fixing member 16, and the pressing force is adjusted easily optionally by changing the screw diameter and the pitch.

摘要： PURPOSE:To uniformalize always normal and reverse reproduced outputs in an auto-reverse tape recorder by constituting a mechanism so that the height and the azimuth of a magnetic head can be adjusted independently in accordance with the magnetic tape reproducing direction. CONSTITUTION:For the purpose of adjusting the height, a height turning lever 25 is fitted to the outside peripheral part of a head sleeve 23 freely turnably, and two height adjusting screws 26a and 26b are engaged with this lever. One of these height adjusting screws 26a and 26b collides with the head of the first reference pin 27, which is stood on a bottom plate 20, by turning of the height turning lever 26. For the purpose of adjusting the azimuth, an aximuth turning lever 28 is fitted loosely to the second supporting rod 24. Azimuth adjusting screws 29a and 29b are engaged with this lever. One of these azimuth adjusting screws 29a and 29b collides with the head of the second reference pin 30 when the azimuth turning lever 28 is turned.

摘要： PURPOSE:To position a magnetic head correctly, by simultaneously reproducing a pair of recording tracks with a magnetic head to be adjusted and utilizing a fact that the frequency signals reproduced from the pair of tracks offset each other when the magnetic head is at a specified vertical position. CONSTITUTION:A magnetic tape 14 is made run at a fixed speed by means of a running mechanism which is not shown in the diagram and a reference tape for adjusting the vertical position of a magnetic head is implemented, by simultaneously recording a normal-phase frequency signal S1 and reverse-phase frequency signal S2 from a signal generator 16 on the magnetic tape 14 in parallel. When the vertical position of a magnetic head 18 is adjusted, the implemented reference tape 17 is made run in the direction of the arrow at a fixed speed and its reference tracks 31 and 32 are respectively reproduced by the recording- reproducing heads 19 and 20 of the magnetic head 18. The reproduced signals are inputted into a 2-phenomena oscilloscope 28 through regenerative amplifiers 26 and 27 and observed. When the magnetic head 18 is adjusted to a specified vertical position, the amplitudes of the reproduced outputs of the signals S1 and S2 become equal to each other and offset each other.

摘要： PURPOSE: To reduce the crosstalk and the noise while realizing high-density recording by setting azimuth angles of respective magnetic heads, which record information on two adjacent recording tracks, in a specific range.
CONSTITUTION: Recording tracks 5a and 5b are recorded and formed alternately on a magnetic tape 4 by magnetic heads 3a and 3b, and head gaps 6a and 6b of magnetic heads 3a and 3b are so formed that they are inclined at angles +θ and -θ respectively in the breadthwise direction of tracks. This azimuth angle θ of tracks is set within a range of 16W22°. If the azimuth angle is set in this range, the crosstalk and the noise are reduced and good recording and reproducing of a minimum block error rate are possible when high-density recording with 10W15μm magnetic head width and 5W10μ track pitch is performed.

摘要： PURPOSE:To facilitate easy control and to save labor, by adjusting the projection degree and height of a magnetic head by means of a single screw and an operation of tools from the same direction. CONSTITUTION:A push screw 9 is turned clockwise and moved downward, and therefore a cone surface 14 pushes the inner fringe of an opening 11 of a substrate 3. Thus the substrate 3 advances to extrude a magnetic head 4 by a prescribed extent, and then a screw 5 is driven tight. Then the screw 9 is turned counterclockwise to move the substrate 3 upward. Thus the surface 14 of a head part 13 is detached from the opening 11, and a flange 12 is fitted to the lower side of the substrate 3 to push up the substrate 3 higher. In such a way, the height of the head 4 can be adjusted. This facilitate easy control for attachment of the head 4 and saves its labor.
