  • Disk drive device having airtight structure with improved airtightness
    Patent number: 8139316
    Abstract: A disk drive device is configured such that a wall of a base plate is provided with a through hole that guides a lead from a drive unit outside. The through hole is covered by a sealing sheet having an insertion hole. The lead is guided from inside the housing via the insertion hole of the sealing sheet. The sealing sheet carries a curable resin. The curable resin, temporarily softened during a curing process, flows into a space between the base plate and the through hole and a space between the insertion hole and the lead. The curable resin is cured in this state, ensuring the airtightness of the housing.
