Magnetic tape head with magnetic head layer formed on base substrate

A magnetic tape head, comprising:

• a base substrate;
• a magnetic head layer formed on said base substrate;
• and
• a closure piece formed on said magnetic head layer,
• wherein an XYZ orthogonal coordinate system is set, taking a thickness direction of said magnetic head layer to be a Y-axis direction, a length direction of said closure piece to be an X-axis direction, and a direction perpendicular to the X-axis direction and Y-axis direction to be a Z-axis direction, and
• when an XY plane passing through a point on the tape bearing surface of said base substrate positioned at a first boundary between said base substrate and said magnetic head layer is taken to be a first plane,
• when an XY plane passing through a point on the tape bearing surface of said magnetic head layer positioned at the first boundary between said base substrate and said magnetic head layer is taken to be a second plane, and
• when an XY plane passing through a point on the tape bearing surface of said closure piece positioned at a second boundary between said magnetic head layer and said closure piece is taken to be a third plane,
• a first distance between said first plane and said third plane is greater than a second distance between said first plane and said second plane.
