Tape Data Recovery - 9 Track Tape
The ‘9 track tape’ refers to a magnetic tape introduced in IBM System/360 mainframe computers. Each 9 track tape consists of 8 data tracks and one parity track, forming a total of 9 parallel tracks. The tape is 1/2-inch wide. Data is stored as 8-bit characters on the entire [...]
Tape Data Recovery - Write Once Read Many (WORM)
Write Once, Read Many (WORM) refers to a type of computer storage system or data storage medium that can be written to only once but read multiple times. Examples of WORM storage media include CD-R and DVD-R. CD writers/burners were known as WORM drives. Some of the [...]
Tape Data Recovery - Quadruplex Videotape
Quadruplex videotape, also known as 2-inch Quad or quad, refers to the 2-inch videotape format introduced by Ampex in 1956. 2-inch quad was the first commercially successful video format. This technology superseded the motion picture film used for kinescopes, and revolutionized the television broadcast operations and productions.

2-inch [...]
Tape Data Recovery - VERA Videotape Format
Vision Electronic Recording Apparatus (VERA) was an earlier type of videotape format developed by British Broadcasting Corporation (BBC) in 1950s. The technology was introduced in 1952, but was not perfected till 1958. During that period, an advanced technology - Ampex quadruplex video recording system - was becoming popular, and [...]
Tape Data Recovery - Helical Scan
Helical scan is a method of tape recording using spinning read/write head and diagonal tracks. The method was invented by Ampex in 1956. It was used in recording TV programs in the 1960s. It is also used in digital audio tapes (DAT). The technology has been used by companies like [...]
Tape Data Recovery - Advanced Intelligent Tape (AIT)
Advanced Intelligent Tape (AIT) is a computer data storage format developed and maintained by Sony. The format is based on magnetic tape storage technology and is characterized by its higher speed and capacity compared to similar technologies such as DLT, LTO, DAT/DDS and VXA. AIT is widely used [...]
Tape Data Recovery - Digital Data Storage (DDS)
Digital Data Storage (DDS) is a format defined by Sony and Hewlett Packard in 1989 for storing computer data. DDS format is evolved from Digital Audio Tape (DAT) technology and uses magnetic tape as medium of data storage. Similar formats available in the market are Linear Tape Open [...]
Tape Data Recovery - Digital Linear Tape (DLT)
Digital Linear Tape (DLT) is a type of magnetic tape data storage technology developed by Digital Equipment Corporation (DEC) in 1984. DLT was first used in MicroVAX II minicomputers. DEC sold the technology to Quantum Corporation in 1994, and since then Quantum has been manufacturing and licensing the [...]
Tape Data Recovery - Linear Tape-Open (LTO)
Linear Tape-Open (LTO) is a form of magnetic tape data storage technology initiated by the LTO Consortium led by Seagate, Hewlett-Packard and IBM in the late 1990s. LTO was developed as an open-standards alternative to the proprietary magnetic tape formats available those days. LTO has been widely used in [...]
Tape Data Recovery - Magneto-Optical Drive
A magneto-optical drive writes data on a magneto-optical disc. Magneto-optical drives do not require a special filesystem. They can be formatted as FAT, HPFS or NTFS. They are available in two models: 130 mm and 90 mm.
Technical Aspects
The 130-mm drive resembles a CD-ROM and is enclosed in an old-style caddy, [...]
