Cartridge Loading Device with Movable Partition for Dual Tape Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cartridge loading devices for magnetic tape cartridges are rigid and designed to accept only a specific size, limiting their ability to accommodate wider tapes, which restricts data storage capacity and requires multiple tape drives or data transfer for legacy formats.
Innovation Solution
A cartridge loading device that can expand to accommodate different tape widths, featuring a housing with guide means and a rotatable locking mechanism to adjust its size and prevent incorrect orientation, allowing a single device to handle various tape sizes while maintaining rigidity for correct orientation prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cartridge loading device is made rigid to prevent incorrect orientation, then cartridge orientation control is improved, but the device cannot accommodate different tape widths
Solution Approach 1:
The cartridge loading device employs a movable partition wall that can shift position between a first position for standard tapes and a second position for wider tapes. This dynamic adjustment mechanism allows the device to adapt its internal geometry to accommodate different tape widths while maintaining rigid constraints for correct orientation through guide rails and engagement features.
2Manufacturing precision
If the device is designed to accept only a specific cartridge size, then manufacturing precision is improved, but the device loses versatility for different tape formats
Solution Approach 1:
The cartridge loading device is designed with a movable partition wall and adjustable guide mechanisms that enable a single device to handle multiple cartridge sizes (e.g., DAT72 and DAT160). The device maintains precise manufacturing tolerances for its adjustable components while providing universal functionality across different tape formats, eliminating the need for multiple specialized devices.
3Device complexity
If conventional rigid loading devices are used, then device simplicity is maintained, but data storage capacity cannot be increased through wider tapes
Solution Approach 1:
The device incorporates a movable partition wall that can be repositioned to accommodate wider tapes, enabling increased data storage capacity. This dynamic feature adds minimal complexity while allowing the device to handle both standard and expanded tape formats, thus increasing storage capability without requiring a complete redesign of the loading mechanism.

AI summary
A cartridge loading device 10 for magnetic tape cartridges includes a first member 12, a second member 14 movable relative to the first member from a first position to a second position and a guide arrangement for guiding movement of the second member between its first and second positions. The guide arrangement includes a projection 38 received in an elongate guide track 32 defining a line of movement having a first end that defines the first position of the second member 14 and a second end that defines its second position. The cartridge loading device also has a locking system that includes a pivotable locking member 82 engageable with the projection 38 for locking the second member in its first position. The cartridge loading device can receive two different sizes of cartridge that correspond to the two positions of the second member. The locking member is actuable by insertion of a cartridge having the larger of two sizes into the device to release the projection to permit movement of the second member from the first position to the second position. The pivotable locking member 82 has a pivot point 92 disposed on a line that is in line with at least a first portion of the line of movement. The first portion extends from the first end of the line of movement.
