Abstract: Techniques are described for predicting data cartridge failure based on analysis of data retrieved from an associated cartridge memory chip. In one embodiment, a system includes a chip reader that retrieves data from a cartridge memory chip of a data cartridge, and a computing device that receives the data from the chip reader, analyzes the data, and generates information regarding a health status of the data cartridge based on the analysis. The analysis may be based on execution of an algorithm that is developed from a set of data, stored in a database, that identifies characteristics of data cartridges with a good health status and differentiates them from data cartridges with a bad health status.

Abstract: A reel flange for a magnetic tape cassette reel has apertures for viewing the tape on the reel. The apertures provide a system for visually estimating the quantity of tape contained on the reel. The flange provides the combined advantages of greater choice of materials for making the flange and improved accuracy in estimating the quantity of tape contained on the reel.
