Storage disk cartridge
First Claim
1. A storage disk cartridge comprising:
- a storage disk;
a shell having first and second main walls generally parallel to the storage disk and encasing the storage disk there between, the storage disk being rotatable within the shell, the shell also having a side wall extending between the first and second main walls;
a head access aperture formed in the side wall, the aperture for enabling a head to be inserted into the shell to be positioned in operative relationship with respect to the storage disk;
a linear shutter mounted to the shell, the shutter being generally linearly movable between a closed position where the shutter covers the aperture and an open position where the shutter exposes the aperture;
a compression spring coupled to the shell and to the shutter and biasing the shutter to the closed position, the compression spring having a helical coil wound around an axis, the axis bending when the linear shutter is moved to the open position, the compression spring further having a first arm coupling one end of the coil to the shell and a second arm coupling the other end of the coil to the linear shutter, the second arm having a bending elbow dividing the second arm into proximal and distal portions, the bending elbow bending when the shutter is moved to the open position.

Abstract
A storage disk cartridge comprises a storage disk, a shell, a linear shutter, and a compression spring. The shell has first and second main walls generally parallel to the storage disk and encasing the storage disk there between. The storage disk is rotatable within the shell. The shell also has a side wall extending between the first and second main walls. A head access aperture is formed in the side wall. The aperture enables a head to be inserted into the shell to be positioned in operative relationship with respect to the storage disk. The linear shutter is mounted to the shell, and is generally linearly movable between a closed position where the shutter covers the aperture and an open position where the shutter exposes the aperture. A compression spring is coupled to the shell and to the linear shutter and biases the shutter to the closed position.

7. A storage disk cartridge comprising:
-
a storage disk selected from a group consisting of a magnetic storage disk and an optical storage disk;
a shell having first and second main walls generally parallel to the storage disk and encasing the storage disk there between, the storage disk being rotatable within the shell, the shell also having a side wall extending between the first and second main walls, the side wall of the shell being generally linear in a direction generally tangential to the storage disk;
a head access aperture formed in the side wall, the aperture for enabling a head to be inserted into the shell to be positioned in operative relationship with respect to the storage disk;
a linear shutter mounted to the side wall of the shell, the shutter being generally linearly movable in the tangential direction along the side wall between a closed position where the shutter covers the aperture and an open position where the shutter exposes the aperture, the linear shutter being a sheet member extending along the first and second main walls and the side wall of the shell, the shutter having first and second wings respectively extending along the first and second main walls and a shutter body interconnecting the first and second wings, the shutter body including a window formed therein, the shutter body covering the head access aperture in the closed position and the window of the shutter body exposing the aperture in the open position;
a compression spring coupled to the shell and to the shutter and biasing the shutter to the closed position, the compression spring having a helical coil wound around an axis, the axis bending when the linear shutter is moved to the open position, the axis being generally coplanar with the storage disk, the compression spring further having a first arm coupling one end of the coil to the shell and a second arm coupling the other end of the coil to the linear shutter, the second arm including a bending elbow dividing the second arm into proximal and distal portions, the bending elbow bending when the shutter is moved to the open position.
