Abstract
Forming a top cover assembly of a disc drive by providing a top cover to a gasket-dispensing device, accelerating a gasket material dispensing head of the gasket-dispensing device over a staging portion of a gasket support portion of the top cover, supplying an uncured gasket material to the accelerating gasket material dispensing head, dispensing a substantially constant increasing thickness gradient of uncured gasket material adjacent the staging portion, discharging a substantially dimensionally uniform bead of the uncured gasket material onto the support surface, applying a substantially constant decreasing thickness gradient of the uncured gasket material adjacent the substantially constant increasing thickness gradient of uncured gasket material and curing the uncured gasket material to form the top cover assembly.
