Abstract: <P>PROBLEM TO BE SOLVED: To provide a micro thin film pinhole mask which has yet been realized.  <P>SOLUTION: Assuming that film stress of Ni is 500 MPa, irrespective of the film thickness, and that the breakage limit of an independent thin film is 1 N/m in total stress, since the thin film reaches the breakage limit when its thickness becomes 2 nm, coating on one side is stopped at thickness of 2 nm or smaller. The coating on one side (front side) is finished at 1nm film thickness (total stress: 0.5 N/m), and then the coating is shifted to the back side. Similarly, the coating on the back side is likewise finished at 1nm film thickness. During this time, the maximum total stress, acting on the independent thin film, is 0.5 N/m which acts when finishing coating on the front side, and the total stress is 0 at the time of double-sided coat. Since the thin film can be coated with a 2 nm thick Ni in total up to here; thereafter when these processes are repeated 75 times, Ni coating of 150 nm thickness can be finished, while the state of maximum total stress of 0.5 N/m or smaller is kept, as it is.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Filed: 2004-04-28
Abstract: <P>PROBLEM TO BE SOLVED: To improve adjustment accuracy by reducing the generation amount of black powder when irradiating a head base with a laser beam and carrying out the height adjustment of a rotary magnetic head.  <P>SOLUTION: The height of magnetic head is adjusted by irradiating an intermediate part between a head fixing section 23 of the head base 21 made of cupronickel and a fixed screw insertion hole 22 with a laser beam and bending the head base 21 of cupronickel by solidification and melting the irradiation section. Although a conventional head base made of brass generates black powder by irradiation of a laser beam and the bending amount of the head base changes from anticipation under the influence and the adjustment accuracy deteriorates significantly, the generation amount of black powder decreases in the head base of cupronickel and at the same time, the bending amount increases sharply by difference in absorptive power of laser. Therefore, when carrying out adjustment of same amount, the generation amount of the black powder decreases remarkably and the adjustment accuracy improves sharply.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
