Claim:
A hermetically resealable hard-disk drive configured for recharging with a low-density gas, said hermetically resealable hard-disk drive comprising: a disk enclosure including a base, and a first cover and a second cover joined to said base by an adhesive layer, said second cover disposed above said first cover; said adhesive layer disposed between said first cover and said second cover and having a periphery smaller than peripheries of said first and second covers and comprising at least one slit, said adhesive layer reinforcing said second cover by bonding said second cover to said first cover; a magnetic-recording disk configured to rotate inside said disk enclosure; a head-slider comprising a magnetic-recording head configured to write data to, and to read data from, said magnetic-recording disk; an actuator configured to move said head-slider above said magnetic-recording disk, and to access said data; a low-density gas, having a density less than air, substantially filling said disk enclosure; a through-hole in said second cover, said through-hole configurable for injection of said low-density gas into said disk enclosure; and a plug press-fitted into and hermetically sealing said through-hole, said plug comprising a flat top portion configured to be flush with an outer surface of said second cover when fitted in said through-hole; wherein said plug is removable to allow recharging said disk enclosure with said low-density gas, and said through-hole is configured to accept a resealing plug to be press-fit into and to reseal hermetically said through-hole after said recharging.
