た。 Generally, when constructing a magnetic head, a head element 2 is housed in a shield case 1 and molded with a resin material 3, as shown in FIG. However, in the case of this configuration, in actual use, the magnetic tape 4 runs in a state of contact as shown by the arrow in FIG.
Due to frictional heat, static electricity, etc. at that time, the coating agent applied to the magnetic tape may adhere to the resin material 3 and fly upward as shown at 4', or cover the front surface of the head element as shown in FIG. There is a problem in that the contact between the magnetic tape 4 and the head element 2 becomes unstable and the original functions such as recording, playback, and erasing cannot be fully performed.

成されている。 An embodiment of the present invention will be described below with reference to FIG. In FIG. 3, 5 is a shield case, and inside this shield case 5 are head elements 6,
Head element protection plates 7 and 8 made of non-magnetic material and also serving as track width regulating plates are housed, and these are molded and fixed with a resin material 9 filled in the shield case 5. In the portions of the shield case 5 located on both sides of the head element 6, grooves 10 extending over the entire width of the shield case 5 are provided.
11 is formed. For example, the grooves 10 and 11 may be formed by inserting a resin material 9 into the shield case 5 to hold the head element 6.
After fixing with a mold, it is formed with a grindstone or the like.

によれば溝をシールドケースの巾全体に亘つて形
成しているため、その溝の形成も非常に簡単であ
るという利点を有する。 As is clear from the above embodiment, the present invention has grooves 10 and 11 extending over the entire width of the shield case in the portions of the shield case located on both sides of the head element.
Therefore, even if the magnetic tape runs while contacting the magnetic head and the coating agent applied to the magnetic tape adheres to the resin material 3 due to frictional heat, static electricity, etc. are grooves 10 and 11
Because it is located inside the head element, it hardly ever pops out or covers the front surface of the head element, unlike in the conventional case, and has the advantage of always exhibiting good recording, playback, and erasing functions. Further, according to the present invention, since the groove is formed over the entire width of the shield case, there is an advantage that the groove can be formed very easily.
