Problems solved by technology

[0015] Therefore, when the magnetic recording medium is magnetically recorded by acting a magnetic field from the magnetic gap portion of the magnetic core 126, the magnetic leakage flux acts from the top end side of the magnetic core 126 to the extension portion 128 side, which affects the recording and reproduction characteristics. danger
That is, if the extension portion 128 is formed to the vicinity of the grinding line K, if a magnetic flux leakage occurs from the top end of the magnetic core 126 to the extension portion 128 side, the magnetic field may leak to the medium sliding surface side and affect the magnetic recording medium. Danger

Embodiment Construction

[0049] Hereinafter, a magnetic head according to an embodiment of the present invention will be described with reference to the drawings.

[0050] Figure 1 to Figure 8 represents the magnetic head of the present invention, Figure 9 ~ Figure 13 Indicates some components constituting the magnetic head, the magnetic head 1 of this embodiment, such as figure 1 and figure 2 As shown, the basic structure of the erasing magnetic head 2 and the main body magnetic head 3 is integrally formed adjacent to the left and right, and the magnetic tape not shown in the figure becomes the magnetic recording medium. figure 1 Swipe in the direction of the arrow in .

[0051] The above-mentioned erasing magnetic head 2 has a box-shaped shielding case 5 with an open back, and an erasing magnetic core assembly 6 housed above it, and a convexly curved medium sliding surface 5A is formed on the front side of the shielding case 5, and is formed on the medium. Inside the window portion 5B on th...

Abstract

Provided is a magnetic head in which accuracy of an attachment position of a magnetic core for a shield case can be improved and dispersion of impedance can be made less. A magnetic core assembly 8 in which a magnetic core 11 is attached to a bobbin 17 provided with a holder 10 is inserted into the inside of a metal shield case 7, the magnetic core assembly 8 is fixed to the inside of the shield case 7 exposing a magnetic gap G at a window part formed at a medium sliding plane of the shield case, and a restrain concave part 7f restrained at one part of the holder 10 and positioning in the direction of height for the shield case 7 of the magnetic gap is formed at at least one part of a side wall inner plane of the shield case 7.

Description

technical field [0001] The invention relates to a magnetic head with a magnetic core structure inside a shielding box with a medium sliding surface, and in particular to a structure capable of improving the positioning accuracy of the magnetic core and the window of the shielding box. Background technique [0002] As an example of an image-related audio control type head, such as Figure 14 , Figure 15 As shown, a magnetic head A formed as follows is known. A pair of C-shaped magnetic cores 100 are prepared on a bobbin 101, and a magnetic core member 103 with a winding portion 102 is formed on the bobbin 101. The above-mentioned magnetic core member 103 , 103 go up and down along one side of the plate-shaped holding case 104 , and then are inserted into the inside of the shielding box 105 . [0003] In addition, for this magnetic head A, a U-shaped pressing member 106 is inserted into the inside of the shield box 105 together with the bobbin 101 to press the magnetic core ...
