Abstract

Disclosed is a mechanism to avoid sealing a breather hole on Hard Disk Drive (hereinafter HDD) in a system. HDD needs to have a breather hole which functions to release delta pressure between HDD inside and outside. When HDD is installed in the system, HDD breather hole should not be sealed. So this disclosed is to make a additional path that a recess by 0.1-0.2mm is enough to avoid sealing it. In case of no additional path design, some boss in system chassis may seal a breather hole. (FIG.2) In case of additional path design, some boss in system chassis could not seal a breather hole (FIG.3,

additional path for HDD breather hole

      Disclosed is a mechanism to avoid sealing a breather hole on Hard Disk
Drive (hereinafter HDD) in a
system. HDD needs to have a breather hole which functions to release
delta pressure between HDD
inside and outside. When HDD is installed in the system, HDD breather
hole should not be sealed.

      So this disclosed is to make a additional path that a recess by 0.1-0.2mm
is enough to avoid sealing it.

      In case of no additional path design, some boss in system chassis may seal
a breather hole. (FIG.2)

      In case of additional path design, some boss in system chassis could not
seal a breather hole (FIG.3,
