Disc Library Storage System with Elastic Buckle Cartridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing database storage systems face challenges in efficiently storing large volumes of data using discs and ensuring disc integrity during replacement, as discs are prone to damage from handling and exposure.
Innovation Solution
A disc library storage system incorporating a disc library, disc drive tower, disc transport device, and disc changing device with a disc cartridge featuring an outer casing and disc tray with elastic buckle structures, allowing for safe and efficient disc replacement and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If discs are manually handled and exposed during replacement, then disc replacement operation is simple, but discs are prone to damage, pollution, and handling errors
Solution Approach 1:
The disc storage system is segmented into multiple independent cartridges, each containing one or more discs. This allows individual cartridge replacement without exposing other discs, maintaining disc integrity while enabling manageable replacement operations.
Solution Approach 2:
Discs are nested within protective cartridges, which are in turn nested within the disc library. This nested structure protects discs from direct exposure and handling damage while allowing systematic replacement at the cartridge level.
2Quantity of substance
If multiple discs are stored and accessed, then data storage capacity increases, but disc handling complexity and exposure risk increase
Solution Approach 1:
Multiple discs are nested within a single protective cartridge, allowing them to be stored and handled as one unit. This reduces the number of times individual discs are exposed to external environment and handling risks while maintaining high storage capacity.
Solution Approach 2:
The cartridge acts as an intermediary between the discs and the external environment. It provides a protected interface for disc insertion and removal, preventing direct exposure and damage to the discs while enabling data access.
3Reliability
If disc replacement frequency increases, then data preservation performance improves, but disc exposure and damage risk increases
Solution Approach 1:
Discs are nested within protective cartridges that remain closed during most operations. Only the necessary cartridge is exposed during replacement, minimizing the exposure time and risk for each disc while enabling frequent data preservation operations.
Solution Approach 2:
Discs are pre-loaded into protective cartridges before being placed in the library. This preliminary protective action ensures discs are never exposed during normal operations, allowing frequent replacement and data preservation without increasing damage risk.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances data preservation capabilities and improves disc replacement efficiency while protecting discs from damage during handling, maintaining high system performance and disc integrity.
Implementation Method 1
The bottom of the disc tray has at least one elastic buckle structure. When the disc tray is received in the outer casing, the elastic buckle structure is buckled in the buckle opening.

AI summary
A disc library storage system and a disc cartridge thereof are provided. The disc library storage system includes a disc library, a disc drive tower, a disc transport device and a disc changing device. The disc library accommodates multiple discs. The disc drive tower accommodates multiple disc drives. The disc drives read data of the discs. The disc transport device moves the discs from the disc library to the disc drive tower and to the disc library. The disc changing device places a disc cartridge including an outer casing and a disc tray. The disc tray accommodates at least one replacement disc. The disc changing device has a pull-out state, in which the disc tray is received in the outer casing, and a close state, in which the disc tray is drawn from the outer casing and the disc transport device unloads the replacement disc from the disc tray.
