Abstract
The magnetic and mechanical property changes of a particulate magnetic disk coating were evaluated as a function of the pigment volume concentration (PVC). It was shown that increased PVC improved the magnetic performance of the magnetic coating. The mechanical properties such as impact strength, gloss, adhesion, and scratch hardness also were measured as a function of increasing PVC. It was found that these coating properties all improved up to a critical pigment volume concentration (CPVC) above which they dramatically decreased. The importance of this CPVC is discussed both from the point of view of its determination, as well as its impact as a limiting factor on the ultimate performance of particulate magnetic disks.
