Abstract
A method for merging the disc pack, E-block and magnet of a disc drive, the disc pack conveyed to a first selected position in a merge assembly station and moved to a merge slide assembly where calibration measurements of disc pack height and squareness are made at a reference position. The merge slide assembly moves the disc pack from the reference position to a shuttled position, the E-block is moved to an E-block nest assembly where the load arms of the E-block are spread in response to the calibration measurements, and the discs of the disc pack are interweaved between opposing read/write heads of the E-block. A magnet slide assembly positions the magnet to straddle the E-block. The disc pack, E-block and magnet are moved together, maintaining the merged interrelationship, to the basedeck and fastened to the basedeck.
