Abstract

Disclosed is a new sealing design for Hard Disk Drive (HDD). The new sealing plate is constituted from damper material existing at the portion sandwiched by Voice Coil Motor (VCM) and Top Cover, and seal material existing at the portion sandwiched by Top Cover and Base Plate. Damper material used between VCM and Top Cover can reduce acoustic in Hard Disk Drive. Conventionally a damper and a seal are attached separately. Therefore, the cost for them is high and the attaching process cannot be simple. This new combined seal, as shown in the Figure, has multi-functions as a damper and a seal. Then, attaching process can be simplified and cost can be reduced.

Combined Sealing Design

      Disclosed is a new sealing design for Hard Disk Drive (HDD).
The new sealing plate is constituted from damper material existing at
the portion sandwiched by Voice Coil Motor (VCM) and Top Cover, and
seal material existing at the portion sandwiched by Top Cover and
Base Plate.  Damper material used between VCM and Top Cover can
reduce acoustic in Hard Disk Drive.  Conventionally a damper and a
seal are attached separately.  Therefore, the cost for them is high
and the attaching process cannot be simple.  This new combined seal,
as shown in the Figure, has multi-functions as a damper and a seal.
Then, attaching process can be simplified and cost can be reduced.
