Quantum Corp
A data storage and management company whose StorNext file system and Scalar tape libraries help businesses and studios store, protect, and archive video and other large files. Founded in 1980 by engineers from IBM and Shugart, Quantum began as a hard disk drive maker, then bought Digital Equipment's storage business in 1994 to add tape technology. Its StorNext is a behind-the-scenes Hollywood workhorse, letting many editors and effects artists work on the same film footage at once.
Estimated from filings — the split-adjusted price range over the quarters each manager built the position. A range, not a fill price; 13F reports a quarter-end snapshot, not a trade date.
