Claim:
A disk drive assembly comprising: a rotatable magnetic disk; a base portion and a cover portion forming an enclosure to enclose said rotatable magnetic disk; a solder channel formed around the perimeter of said enclosure; a solder preform seal disposed within said solder channel, said solder preform seal hermetically sealing said base portion with said cover portion without requiring welding of said base portion to said cover portion; said solder preform seal is a solid at room temperature and has a melting temperature that is lower than a melting temperature of said cover portion or said base portion, such that said solder preform seal can be re-flowed within said solder channel without melting said cover portion or said base portion; and a solder containment barrier gasket formed on both sides of said solder channel to prevent said solder preform seal from flowing out of said solder channel when heated.
