The Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
Linear Tape-Open (LTO), also known as the LTO Ultrium format, [1] is a magnetic tape data storage technology used for backup, data archiving, and data transfer. It was originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats available at the time.
File archiver and backup tools have been created to pack multiple files along with the related metadata into a single tape file. Serpentine tape drives (e.g., QIC) offer improved access time by switching to the appropriate track; tape partitions are used for directory information.

The IBM implementation of this file system has been released as the open-source IBM Linear Tape File System — Single Drive Edition (LTFS-SDE) product. The Linear Tape File System uses a separate partition on the tape to record the index meta-data, thereby avoiding the problems associated with scattering directory entries across the entire tape.
Digital Linear Tape (DLT; previously called CompacTape) is a magnetic-tape data storage technology developed by Digital Equipment Corporation (DEC) from 1984 onwards. In 1994, the technology was purchased by Quantum Corporation , who manufactured drives and licensed the technology and trademark.
Cassette tape, a two-spool tape cassette format for analog audio recording and playback and introduced in 1963 by Philips; DC-International, a format that was created by Grundig after Phillips had abandoned an earlier format that was being created alongside the Compact Cassette; 8-track tape, continuous loop tape system introduced in 1964
A DDS cartridge uses tape with a width of 3.81mm, with the exception of the latest formats, DAT-160 and DAT-320, both which use 8mm wide tape. Initially, the tape was 60 meters (197 feet) or 90 meters (295 ft.) in length. Advancements in materials technology have allowed the length to be increased significantly in successive versions.
