Our Story
Four decades of tape library leadership.
Qualstar began in 1984 and has focused on magnetic tape libraries for decades. In 1995 the company focused on the design and manufacturing of magnetic tape libraries and drives, delivering secure and reliable solutions for long retention cycles. As the last independent tape library manufacturer, Qualstar avoids slot licensing fees and provides flexibility across archive software stacks.

Tape market context · 2024–2025
Tape capacity shipments hit a record 176.5 EB in 2024 — up 15% year over year.
Industry shipment data shows tape is being purchased into modern AI-scale and cyber-resilient architectures, not maintained as legacy. Qualstar's Q Series is built for that growth.
