Patent ID: 7457079

Claim:
A magnetic head assembly for a helical scan drive comprising: a magnetic recording head, having a leading side and a trailing side relative to the traveling direction of a magnetic recording medium and fabricated in a thin film forming process, at least one auxiliary member adhered to either said leading side or said trailing side of said magnetic recording head, said magnetic recording head mounted in a helical scan drive and including: a substrate, a first magnetic core formed above said substrate and having a substantially rectangular-shaped front end face, a second magnetic core formed above said substrate and having a front portion, a substantially rectangular-shaped front end face, and a back portion, said back portion being connected to said first magnetic core, a magnetic gap of predetermined thickness provided between said front end face of said first magnetic core and said front end face of said second magnetic core, a planar spiral coil having a portion thereof disposed between said first magnetic core and said second magnetic core for developing a magnetic flux between the first and second magnetic cores, wherein a width of said second magnetic core front end face is smaller than a width of said first magnetic core front end face; and wherein the planar spiral coil is rectangular-shaped and a portion of the coil between widened portions of the magnetic cores is at a longer side of the rectangular-shaped planar spiral coil.
