Rattle reduction mechanism in a removable cartridge for a disk drive

A cartridge for use in a disk drive, the cartridge comprising:

• a shell defining an interior volume and an inclined surface, the shell having a leading edge, a back edge, and two side edges, the leading edge defining a cartridge door port and a door control port, the door control port being proximal to a junction of the leading edge and one of the side edges, the shell defining a passage extending in a direction substantially parallel to the two side edges,
• a rotatable disk disposed within the interior volume, the disk including a substantially planar recording medium and a central hub, the inclined surface being non-parallel to the planar recording medium;
• a door rotatable between a closed position and an open position, the door covering a first portion of the cartridge door port when the door is in the closed position, the door not covering the first portion of the cartridge door port when the door is in the open position;
• and
• a door opening link having a door end and a passage end, the door end being coupled to the door, the passage end being movable within the passage in a direction substantially parallel to the side edges between a closed location and an open location, the closed location being proximal to the door control port, the door being in the closed position when the passage end is in the closed location, the door being in the open position when the passage end is in the open location;
• a member that is movable between a contact position and a non-contact position, a first portion of the member contacting the hub when the member is in the contact position, the first portion of the member being spaced apart from the hub when the member is in the non-contact position, the member rotating about an axis between a non-contact rotational orientation and a contact rotational orientation as the member moves between the non-contact position and the contact position, the member moving in a direction substantially parallel to the axis between a non-contact axial location and a contact axial location as the member moves between the non-contact position and the contact position, a second portion of the member contacting at least a portion of the inclined surface as the member moves between the non-contact position and the contact position.

A cartridge for use in a disk drive, the cartridge comprising:

• a shell defining an interior volume and a first surface, the shell having a leading edge, a back edge, and two side edges, the leading edge defining a cartridge door port and a door control port, the door control port being proximal to a junction of the leading edge and one of the side edges, the shell defining a passage extending in a direction substantially parallel to the two side edges,
• a rotatable disk including a substantially planar recording medium and a central hub, the recording medium being disposed within the interior volume, the first surface being non-parallel to the planar recording medium;
• a door mounted within the shell, the door being rotatable about a pivot point between a closed position and an open position, the door covering at least a first portion of the cartridge door port when the door is in the closed position, the door not covering the first portion of the cartridge door port when the door is in the open position;
• a door opening link having a first end and a second end, the first end being coupled to the door proximal to the pivot point, the second end being movable within the passage in a direction substantially parallel to the side edges between a closed location and an open location, the closed location being proximal to the door control port, the door being in the closed position when the second end is in the closed location, the door being in the open position when the second end is in the open location;
• and
• an anti-rattle device that is movable between a first position and a second position, the device rotating about an axis between a first rotational orientation and a second rotational orientation as the device moves between the first position and the second position, the device moving in a direction substantially parallel to the axis between a first axial location and a second axial location as the device moves between the first position and the second position, a portion of the device contacting at least a portion of the first surface as the device moves between the first position and the second position, the device contacting the disk and a portion of the disk contacting a portion of the shell when the device is in the second position, the device applying more pressure to the disk when the device is in the second position than when the device is in the first position.

A removable cartridge, comprising:

• a shell defining an interior volume and a first surface;
• a rotatable disk including a substantially planar recording medium and a central hub, the recording medium being disposed within the interior volume, the first surface being non-parallel to the recording medium;
• an anti-rattle device that is movable between a first position and a second position, the device rotating about an axis between a first rotational orientation and a second rotational orientation as the device moves between the first position and the second position, the device moving in a direction substantially parallel to the axis between a first axial location and a second axial location as the device moves between the first position and the second position, a portion of the device contacting at least a portion of the first surface as the device moves between the first position and the second position, the contact between the device and the first surface causing the device to move from the first axial location to the second axial location as the device rotates from the first rotational orientation to the second rotational orientation, the device contacting the disk and a portion of the disk contacting a portion of the shell when the device is in the second position, the device applying more pressure to the disk when the device is in the second position than when the device is in the first position.

A removable cartridge, comprising:

• a shell defining an interior volume and further defining an inclined surface;
• a rotatable disk including a central hub and a substantially planer recording medium secured to the central hub, the central hub defining a central aperture for engagement with a spindle motor of a disk drive unit, and the recording medium being disposed within the interior volume of the shell;
• and
• a member having a first portion and a second portion, the first portion of the member contacting the inclined surface of the shell such that as the member rotates about an axis, the inclined surface moves the member axially along the axis, the member being rotatable about the axis between a contact position and a non-contact position, the second portion of the member contacting a portion of the hub when the member is in the contact position, and the member being spaced apart from the hub when the member is in the non-contact position, wherein the member restricts movement of the disk more when the second portion of the member contacts the hub than when the second portion of the member is spaced apart from the hub.
