Inventor: DUMAS WILLIAM VINCENT
IPC: C08G73/10
Filed: 1990-12-24
Abstract: A polyimide surface is pretreated in preparation for an adhesion promotion treatment and subsequent metallization on the surface, wherein the pretreatment comprises the steps of:
     (A) contacting the polyimide surface with an aqueous solution of nitric acid having a concentration of about 35 to about 70% by weight or an aqueous solution of hydrochloric acid having a concentration of about 10 to about 38% by weight;   (B) rinsing the acid-treated polyimide surface with water so as to substantially remove the acid from the surface of the polyimide;   (C) contacting the rinsed polyimide surface with a mild etching agent, resulting in the formation of a residual film on the polyimide surface;   (D) contacting the etched polyimide surface with a basic solution, and   (E) removing the residual film formed on the surface of the polyimide after contact with the mild etching agent in step (C).   
     The method of this invention allows both filled and unfilled polyimide substrates to be electroless plated in a consistent manner and provides improved adhesion between the polymer and subsequently deposited metals.

Abstract: In a magnetic disk apparatus, a magnetic disk has a plurality of servo sectors. Coarse and fine position data as servo data for positioning a magnetic head are recorded on each servo sector. The coarse position data is constituted by bit cells for identifying each data track and arranged in a track direction. Each bit cell represents a first or second value. Flux change occurs only at a boundary portion of a bit cell. Flux change occurs at leading edges of bit cells for every other bit in the same direction. Flux change does not occur at a central portion of a bit cell representing the first value, but occurs at a central portion of a bit cell representing the second value. Flux change occurs at the central portion of the bit cell in a direction opposite to that of flux change at the leading edge of a bit cell. The fine position data is constituted by two types of data respectively recorded at positions deviated from a central line of each data track toward the center of the disk and deviated toward the outer periphery of the disk such that a manner that a difference in amplitude between read signals serves as a function of a small positional deviation.
