Abstract
A magnetic head having a recording and/or reproducing magnetic gap and an erasing magnetic gap for writing and/or reading informational signals on and/or from a flexible disk is disclosed. A magnetic circuit comprises a front core having center cores and side cores and a rear core. The front core is sandwiched between a pair of sliders for assuring contact with the flexible disk. At least one of the sliders is provided with core reinforcing portions in positions corresponding to the cores and the side cores of the front core. The core reinforcing portions are in contact with the center cores and the side cores for reinforcing these cores.
Claims9
A magnetic head, comprising:
- a front core including a pair of side cores and center cores interposed between the pair of side cores so that first and second magnetic gaps are formed between the side cores and the center cores;
- a rear core having a center leg and side legs which contact with the center cores and the side cores of the front core;
- coil bobbins having core through-holes into which the side cores and the side legs of the front and rear cores are inserted;
- and
- a pair of sliders which sandwich the front core therebetween;
- wherein at least one of the sliders is provided with core reinforcing portions which contact with the center cores and/or the side cores of the front core for reinforcing the same, in which the side cores of the front core and the core reinforcing portions of the sliders which contact with the side cores of the front core are positioned within the core through-holes of the coil bobbins and are in surface contact with each other.
