  • Media drive cage having improved insertion shock and air flow properties
    Patent number: 7187541
    Abstract: A slot in a media drive cage receives a protrusion of a media drive housing. A spring adjacent to the slot engages the protrusion just before it reaches the end of the slot, causing the media drive to slow down prior to reaching a fully engaged position within the cage. The frictional slowing reduces mechanical shock to the drive when its movement stops. A resilient finger at the end of the slot further reduces shock. A resilient latch retains the drive within the slot. To remove the drive, the latch may be disengaged by pulling on a hook portion of the latch. The slot may be nonlinear to enable airflow through the slot and over the drive, thus facilitating cooling of the drive.
