Abstract
PURPOSE: To avoid the flaw of magnetic tape, by regulating the gap between the shield case and the core holder and between the core and the core holde for the provision of melt-sprayed film on the sliding surface so that the groove or hole can not be caused on the slide surface.
CONSTITUTION: The gap A betwen the window 11 of the shield case 1 and the core holder 4, and the gap B between the core holder 4 and the cores 3, 3', are respectively formed as ≤0.2mm to grow the plasma melt-sprayed film 8 at the tape sliding surface. By the regulation of the gap, as the thickness of the melt-sprayed film becomes thicker, growing is made to avoid the gap 6 as C. Thus, even with thin melt-sprayed film 8, since the gaps A and B are covered, no groove or hole can be produced after shaping.
