Magnetic Tape Systems


There are three types of format for magnetic tape systems: LTO, which is an open format, and the two independent formats each developed by IBM and Oracle.

Roadmap for Magnetic Tape Systems

IBM's 3592 TS series and Oracle's T10000 series tape drives are currently in development. They have their own standards and feature large capacity, high transfer speeds, and high reliability, etc.
Tape media are developed for each series drive, and are not compatible with each other. However, compatibility is maintained among several generations. In addition, they have a characteristic whereby a previous-generation medium can have a larger storage capacity when formatted on a later-generation drive than when formatted on the previous-generation drive.

* The backward compatibility and reuse-formatted capacity vary depending on the product and its generation. For details, please contact the manufacturer of each system.

LTO (Linear Tape Open)

LTO (Linear Tape Open) is a magnetic tape storage technology established jointly by Hewlett-Packard, IBM, and Quantum in 1997, as a new open standards alternative to the proprietary magnetic tape formats that were available at the time. This open standard has been recognized for its compatibility and reliability and is now the most common magnetic tape device world wide. Since it’s a open format, LTO is widely used with small and large computer systems.

● LTO Standards and Roadmap

● Compatibility of LTO-based products

The LTO-based products are compatible with the previous two generations. Compatibility is maintained even between the drives/media produced by different manufacturers.
