CDC used IBM-compatible 1 ⁄ 2-inch (13 mm) magnetic tapes, but also offered a 1-inch-wide (25 mm) variant, with 14 tracks (12 data tracks corresponding to the 12-bit word of CDC 6000 series peripheral processors, plus 2 parity bits) in the CDC 626 drive. [10] Early IBM tape drives, such as the IBM 727 and IBM 729, were mechanically ...
DDS tape drive (bottom). Above, from left to right: DDS-4 tape (20 GB), 112m Data8 tape (2.5 GB), QIC DC-6250 tape (250 MB), and a 3.5" floppy disk (1.44 MB). A tape drive is a data storage device that reads and writes data on a magnetic tape. Magnetic-tape data storage is typically used for offline, archival data storage. Tape media generally ...
Stand-alone tape management systems are predominant on mainframe platforms where tape is used as both a backup and base load storage medium.. Mainframe systems such as IBM's z/OS do provide some basic support for tape inventory control via the OS Catalog but as cataloging files is optional it is usually required that an additional software package does the following:
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.
Subsequently, tape libraries became physically automated, and as such are sometimes called a tape silo, tape robot, or tape jukebox. These are a storage devices that contain one or more tape drives , a number of slots to hold tape cartridges , a barcode reader to identify tape cartridges, and an automated method for loading tapes (a robot).
Digital Data Storage (DDS) is a computer data storage technology that is based upon the Digital Audio Tape (DAT) format that was developed during the 1980s. DDS is primarily intended for use as off-line storage, especially for generating backup copies of working data.
