Tandberg Data Assigned Patent

Tandberg Data Holdings, Luxembourg, has been assigned a patent (8,156,292) developed by Matthew D. Bondurant, Superior, CO., S. Christopher Alaimo, Boulder, CO, and Chris Mayne, Boulder, CO, for "methods for implementation of data formats on a removable disk drive storage system."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "An archiving system including one or more removable disk drives embedded in removable disk cartridges, referred to simply as removable disk drives. The removable disk drives allow for expandability and replacement such that the archiving system need not be duplicated to add new or more storage capacity. In embodiments, the removable disk drives store metadata that contain information about the data stored on the removable disk drive. The metadata allows the system to retrieve the correct data from the random access memory and establishes controls on the data stored on the removable disk drive. In embodiments, the metadata is stored in two locations, such that, if the metadata in one location is corrupted, the second copy of the metadata may be retrieved."

The patent application was filed on January 4, 2011 (12/984,550).
