Method for assembling a disk drive

A method for assembling a disk drive, wherein said disk drive comprises a base plate with a push-pin hole, a first data storage disk, and an actuator arm assembly, wherein said method comprises the steps of:

• executing a servo writing operation on said first data storage disk, wherein said executing step comprises disposing a push-pin through said push-pin hole in said base plate, engaging said push-pin against said actuator arm assembly, and moving said push-pin along said push-pin hole to dispose said actuator arm assembly at a predetermined radial position relative to said first data storage disk;
• withdrawing said push-pin from said push-pin hole after said executing a servo writing operation step;
• and
• disposing a filter within said push-pin hole after said withdrawing step.

A method for assembling a disk drive that comprises a first data storage disk, a base plate, and a push-pin hole on said base plate, wherein said method comprises the steps of:

• executing a servo writing operation on said first data storage disk, wherein said executing step comprises disposing a push-pin through said push-pin hole, wherein said first data storage disk comprises a perimeter, wherein a projection of said perimeter onto said base plate of said disk drive defines a first region on said base plate, and wherein said push-pin hole is totally contained within said first region on said base plate;
• withdrawing said plush-pin from said push-pin hole;
• and
• installing a filter in said push-pin hole after said withdrawing step, wherein said filter comprises a filter housing, and wherein said filter housing comprises at least one inlet and at least one outlet with a filtering material disposed therebetween.

A method for assembling a disk drive that comprises a first data storage disk, a base plate, and a push-pin hole on said base plate, wherein said method comprises the steps of:

• executing a servo writing operation on said first data storage disk, wherein said executing step comprises disposing a push-pin through said push-pin hole from an exterior side of said base plate;
• withdrawing said push-pin from said push-pin hole;
• and
• installing a filter in said push-pin hole from said exterior side of said base plate.
