Title: Production of thin film magnetic head
Inventor: SASAKI KENJI
IPC: G11B5/31
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To form a uniformed shape of an insulating layer and to obtain a production process with stable quality by forming a lower magnetic pole having a cross section of U-shape on a substrate, forming a thin film coil by coating the lower magnetic pole with an insulating film to cover the center of the U-shaped part, and forming a bridge on the upper part of the lower magnetic pole to form an upper magnetic pole having a linear cross section which constitutes a closed magnetic circuit with the lower magnetic pole. SOLUTION: An aluminum layer 12 having enough thickness is formed on a substrate 11. Then the aluminum layer 12 is patterned with a resist to form recessed part where a coil is to be housed and the aluminum layer 12 is etched with argon ion. Since aluminum has an extremely high etching rate compared to Al2 O3 , namely, Al oxide in the etching process, the aluminum layer 12 having a deep recess 14 can be immediately obtd. It is required to convert the aluminum layer 12 into an insulating layer 16 because the aluminum layer 12 as it is a conductive material and it is not appropriate to directly form a lower magnetic pole 15 on the aluminum layer 12.

IPC: G06T5/30
Filed: 1989-11-10
Abstract: PURPOSE:To enable a high-speed processing by executing the enlargement and reduction processings of a picture only to border points between a recognition object and the background. CONSTITUTION:The enlarge and reduction processings are executed by binarizing the multiple density picture which is obtained by picking up the image of the recognition object by an image pickup means, extracting a border dot sequence as the border between the recognition object and the background and filling up the inside of a 3X3 filter 4 with the border point as a reference point by the same value as a point in a part 1 (enlargement processing) or by the same value as a background point (reduction processing). Thus, without scanning the background, where the recognition object 1 does not exist, or the internal part of the recognition object 1 not to be the border point, it is enough only to execute the enlargement and reduction processings to the border point of the recognition object 1 and accordingly, processing speed can be widely increased.
