Method for manufacturing a magnetic head core having a magnetic film

A manufacturing method of a magnetic head core, comprising:

• (a) a first step of forming a first surface on a magnetic block which is made of a first magnetic material of high permeability;
• (b) a second step of depositing a first magnetic film made of a second magnetic material of high saturation magnetic flux density on the first surface;
• (c) a third step of forming a second surface arranged to be oblique to the first surface on the first magnetic film;
• (d) a fourth step of depositing a nonmagnetic film made of a nonmagnetic material for serving as a magnetic gap on the second surface;
• (e) a fifth step of depositing a second magnetic film made of the second magnetic material on the nonmagnetic film deposited on the second surface;
• (f) a sixth step of bonding a reinforcing block with the second magnetic film deposited on the nonmagnetic film, the reinforcing block including a nonmagnetic exposure portion, and said sixth step follows said fifth step;
• and
• (g) a seventh step of forming a magnetic head core which includes the magnetic block, the first magnetic film, the nonmagnetic film, the second magnetic film and the reinforcing block, so that the nonmagnetic exposure portion exposes to a sliding surface for sliding a recording medium of the magnetic head core.

A manufacturing method of a magnetic head core, comprising;

• (a) a first step of forming a groove for winding in one surface of a magnetic block which is made of a first magnetic material of high permeability;
• (b) a second step of depositing a first magnetic film made of a second magnetic material of high saturation magnetic flux density on a portion excluding the inside of the groove on the surface of the magnetic block where the groove is formed;
• (c) a third step of depositing a nonmagnetic film made of a nonmagnetic material for serving as a magnetic gap on the first magnetic film deposited on the surface of the magnetic block;
• (d) a fourth step of depositing a second magnetic film made of the second magnetic material on the nonmagnetic film deposited on the first magnetic film;
• (e) a fifth step of bonding a reinforcing block with the second magnetic film deposited on the nonmagnetic film, the reinforcing block including a nonmagnetic exposure portion, and said fifth step follows said fourth step;
• and
• (f) a sixth step of forming a magnetic head core which includes the magnetic block, the first magnetic film, the nonmagnetic film, the second magnetic film and the reinforcing block, so that the nonmagnetic exposure portion exposes to a sliding surface for sliding a recording medium of said magnetic head core.
