Dual disc drive actuator assembly fabrication
First Claim
1. A method for fabricating a dual actuator assembly having first and second rotatable actuator assemblies which are axially aligned for independent rotation about a common axis and supporting at least first and second read/write heads, respectively, comprising steps of:
- (a) providing a dual bearing cartridge assembly comprising a stationary shaft aligned along the common axis having first and second ends, a first rotatable sleeve mounted for rotation about the stationary shaft toward the first end, a second rotatable sleeve mounted for rotation about the stationary shaft toward the second end, and first and second bearing assemblies supporting the first and second rotatable sleeves, respectively;
(b) inserting a support member between the first and second rotatable sleeves to provide a supporting force in opposition to the preload of the first and second bearing assemblies; and
(c) attaching the first and second actuator assemblies to the first and second rotatable sleeves, respectively.

Abstract
A method for fabricating a dual actuator assembly for a disc drive. The dual actuator assembly has first and second rotatable actuator assemblies which are axially aligned for independent rotation about a common axis and support at least first and second read/write heads, respectively. The method comprises providing a dual bearing cartridge assembly with a stationary shaft aligned along the common axis having first and second ends, a first rotatable sleeve mounted for rotation about the stationary shaft toward the first end, a second rotatable sleeve mounted for rotation about the stationary shaft toward the second end, and first and second bearing assemblies supporting the first and second rotatable sleeves, respectively. A support member is inserted between the first and second rotatable sleeves to provide a bearing support force in oppostion to the preload force of the first and second bearing assemblies, allowing attachment of the first and second actuator assemblies to the first and second rotatable sleeves, respectively while preventing damage to the bearing assemblies.
