US 4,539,616 A · Thin film magnetic head and fabricating method thereof

Abstract

Herein disclosed is a thin film magnetic head which is so constructed that a conductor layer arranged in a non-magnetic insulating layer isolating two magnetic poles and adapted to form a coil of plural turns has a height made larger than the width and gap thereof. A method of fabricating that head includes the step of forming a non-magnetic insulating layer, the step of etching the insulating layer by using a mask layer formed thereover as a mask, the step of depositing a metal for providing a conductor layer, the step of removing the mask layer together with the metal thereover, and the step forming a coating of a non-magnetic insulating layer thereover, thereby to form the conductor layer. The head thus fabricated has its magnetic recording and reproducing characteristics improved.

Dependent claims

A thin film magnetic head comprising:

first and second magnetic pole layers;
a non-magnetic insulating layer sandwiched between at least said first and second magnetic pole layers;
said first and second magnetic pole layers forming an operation gap through said insulating layer;
and a conductor layer disposed in said insulating layer and forming a coil of plural turns, with each turn of said coil having a height in a direction extending from the first to the second magnetic pole layer and having a width, and with a space between successive turns of the coil, and wherein the height of each turn is made larger in at least a portion of said coil than the width of said turn and than the space between said turn and an adjacent turn.
