Contactless IC Memory for Table of Contents Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated data storage libraries require additional resources and manual mounting of media to access table of contents information for data stored on removable media, which is inefficient and resource-intensive.
Innovation Solution
Implementing a mechanism to store and retrieve application-specific table of contents information using contactless integrated circuit (IC) memory on data storage cartridges, allowing access without mounting the media, through RF communication and index partition parsing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If table of contents information is stored on removable media and accessed through mounting the media in a drive, then the information can be retrieved, but additional resources are required and manual mounting is needed which is inefficient
Solution Approach 1:
The patent extracts the table of contents information from the removable media and stores it separately in cartridge memory. This allows the TOC information to be accessed independently without mounting the entire media in a drive, eliminating the need for manual mounting operations and reducing resource requirements while maintaining productivity
Solution Approach 2:
The patent introduces cartridge memory as an intermediary storage component that holds table of contents information. This intermediary allows quick access to metadata without requiring the physical presence or mounting of the actual removable media, thus improving efficiency while reducing the complexity of media handling operations
2Loss of time
If table of contents information is stored in cartridge memory, then access is rapid and resource-efficient, but the media must be mounted in a drive to access the actual data
Solution Approach 1:
The patent performs preliminary action by pre-storing table of contents information in cartridge memory before the media needs to be accessed. This allows the system to quickly retrieve metadata and prepare for data access without waiting for media mounting operations, thereby reducing access time while the media mounting step remains necessary for actual data retrieval
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
Enables rapid and resource-efficient access to file information without the need for physical media mounting, improving data retrieval and storage management in automated data storage libraries.
Implementation Method 1
The CM information may be accessed through the drive interface, or the information may be accessed through a CM reader/writer, which accesses the CM through radio frequency (RF) communication.

AI summary
Method, system, and computer program product embodiments for recording data on a contactless integrated circuit (IC) memory associated with a data storage cartridge are provided. In one exemplary embodiment, subsequent to an insertion of a data storage cartridge, a consistency is verified between a TOC written to a contactless IC memory and an index, wherein if the TOC and the index are inconsistent, a TOC profile file is refreshed with data from the index. The TOC is written to the contactless IC memory.
