Abstract

PURPOSE:To easily make the position adjusting operation of plural magnetic heads, by turning a head holding body holding the plural magnetic heads against a supporting body around a fulcrum and fixing the holding body at an optional position by means of adjusting screws installed to both sides of the fulcrum. CONSTITUTION:Recording by means of a magnetic head 8 and reproduction by means of another magnetic head 9 are performed at every one track, by causing cores 10 and 11 of magnetic heads 8 and 9 to touch a running magnetic tape while the magnetic tape is supported by a tape guide face 13 and moving a supporting body 1 upward and downward together with the head holding body 2. When the magnetic tape is loaded, positions of the cores 10 and 11 are checked and, when both the cores 10 and 11 are not positioned on the same track, the head holding body 2 is turned around a fulcrum 4 by rotating a right and left adjusting screws 7 and fixed at an optional position by pressing fitting pieces 6 with the head section of the screws 7. Since this adjusting work can be performed while recording/reproducing signals are checked, the adjustment can be performed at once.

録。Technical background of the invention and its problems Conventionally, a plurality of magnetic heads are brought into contact with a running magnetic tape, and data processing is performed for each read track by relatively moving these magnetic heads in the width direction of the magnetic tape. There are magnetic recording devices that do this. However, when the number of tracks is increased, the width of the tracks becomes narrower. For example, when a 1/2 inch wide magnetic tape is subdivided into 200 tracks, the track width is narrowed to about 0.05 + m++ to allow some margin on both sides for recording.

Then, by turning the adjustment screw, the head holder is swung and fixed at a desired position, thereby positioning a plurality of magnetic heads relative to the magnetic tape on the same rack, and thus removing the magnetic heads. The structure is such that the position can be adjusted extremely easily without any trouble.

Reference numeral 1 denotes a support that is connected to a lifting device (not shown) to lower the stomach, and a head holder 2 is provided on two sides of the support 1.

Attachment holes 6 are formed in the holes 6, and adjustment screws 7 inserted through these holes 6 are screwed onto the support holder 1.

．． 1' is touched to the magnetic tape, the support 1 is moved up and down together with the head holder 2, and recording by the magnetic head 8 or reproduction by the magnetic head 9 is performed track by track. In this case, it is not possible to equalize the amount of adhesive between the core 10.11 and the tape base 12, and due to variations in other dimensions, the two cores 10.11 cannot be placed on the same rack of magnetic tape. It is extremely difficult to locate it.

すようなわずられしさをともなうことがない。If the cores 10 and 11 are not located on the same track when checked in the mounted state, turn the left and right adjustment screws 7 to swing the head holder 2 around the fulcrum 4, and then move the mounting piece 6 to an arbitrary position. is held down by the head of the adjusting screw 7 to fix the head holder 2. This adjustment work can be carried out while checking the recorded or reproduced signal with a B° detector, so the adjustment can be completed in one go, and there is no need for the trouble of removing the head base 12 from the head holder 2.

うことができる。Note that if the cores 10.11 are glued one by one to the head base 12, as described above, variations in the mounting height of the cores 10.degree. II to the head base 12 will increase due to changes in the amount of adhesive. Two block-shaped magnetic bodies are fixed with adhesive, and this adhesive is sliced to form the core 10.
．． To obtain a combined body of cores 10.11, the thicknesses of cores 10.11 are at least equal to each other. In the state of the II combination, the cores 10.11 can be aligned in the same plane. Although not shown, this is an extremely effective means when three cores including the erase head are arranged in parallel. However, even when a plurality of magnetic bodies are bonded together and then sliced to form a composite body of a plurality of cores, and this is bonded to the head base 12, the thickness of the adhesive film differs partially. Again, variations occur in the mounting heights of the individual cores with respect to the head base 12. However, as described above, it is extremely easy to align two or three cores on the same track simply by turning the adjustment screw 7.

もよい。Next, other embodiments showing the fulcrum structure of the head holder 2 are shown in FIGS. 3 to 5. Figure 3 shows the head holder 2.
4 has a fulcrum 17 with a triangular cross section that supports the lower surface of the head holder 2. In FIG. 5, a round bar is fixed to the lower surface of the head holder 2 to form a fulcrum 18. Of course, the fulcrum 18 may be formed by fixing a round bar to the upper surface of the support 1.

容易に行なうことができる効果を有する。Effects of the Invention Since the present invention is configured as described above, by swinging the head holder around the fulcrum and fixing it at an arbitrary position with the adjustment screw, multiple magnetic heads can be mounted without removing the magnetic heads from the head holder. This has the effect that the magnetic tape can be positioned on the same track on the magnetic tape, and the position adjustment work can be performed extremely easily.
