IBM Sets New Record for Magnetic Tape Storage; Makes Tape Competitive for Cloud Storage

A press release out of the company states, “IBM Research scientists have achieved a new world record in tape storage – their fifth since 2006. The new record of 201 Gb/in2 (gigabits per square inch) in areal density was achieved on a prototype sputtered magnetic tape developed by Sony Storage Media Solutions. The scientists presented the achievement today at the 28thMagnetic Recording Conference (TMRC 2017) here. Tape storage is currently the most secure, energy efficient and cost-effective solution for storing enormous amounts of back-up and archival data, as well as for new applications such as Big Data and cloud computing. This new record areal recording density is more than 20 times the areal density used in current state of the art commercial tape drives such as the IBM TS1155 enterprise tape drive, and it enables the potential to record up to about 330 terabytes (TB) of uncompressed data* on a single tape cartridge that would fit in the palm of your hand. 330 terabytes of data are comparable to the text of 330 million books, which would fill a bookshelf that stretches slightly beyond the northeastern to the southwestern most tips of Japan.”

The release goes on, “Magnetic tape data storage is currently experiencing a renaissance. With this achievement, IBM scientists demonstrate the viability of continuing to scale the tape roadmap for another decade. ‘Tape has traditionally been used for video archives, back-up files, replicas for disaster recovery and retention of information on premise, but the industry is also expanding to off-premise applications in the cloud,’ said IBM Fellow Evangelos Eleftheriou. ‘While sputtered tape is expected to cost a little more to manufacture than current commercial tape that uses Barium ferrite (BaFe), the potential for very high capacity will make the cost per TB very attractive, making this technology practical for cold storage in the cloud’.”
