ABSTRACT:
A process for assembling a disk cartridge is disclosed. The process includes the steps of snapping a top shell half of the disk cartridge over a bottom shell half of the disk cartridge; adjusting the shell halves until the shell halves are in abutment contact with each other at a weld site; and directing an energy beam at the weld site until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. The process is repeated for each of a plurality of weld sites located on the perimeter of the disk cartridge. A process for assembling a disk cartridge is disclosed in which an energy beam is split into a plurality of split energy beams. The plurality of split energy beams are focused on a plurality of weld sites until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. A disk cartridge prepared by either of the above described processes is also disclosed.
