IBM Sets Record in Magnetic Tape Data Density

IBM developed magnetic tape data density of 29.5 billion bits per square inch - about 39 times the industry standard

IBM researchers announced they have demonstrated a world record in areal data density on linear magnetic tape — a significant update to one of the computer industry's most resilient, reliable and affordable data storage technologies.

This breakthrough proves that tape technology can increase capacity for years to come, which has important implications, as tape storage systems are more energy efficient and cost-effective than hard disk drive storage systems.

Businesses and governments use magnetic tape to store, protect and access large volumes of important data, including: data and video archives, back-up files, replicas for disaster recovery, and retention of information required for regulatory compliance.
