Tape Data Recovery - UNISERVO
UNISERVO was the primary I/O device on the UNIVAC I, the first commercial computer manufactured in the United States. Thus UNISERVO was widely accepted as the first tape drive for a commercial computer.
Architecture
UNISERVO consisted of a ½-inch wide metal tape made of nickel-plated phosphor bronze. Data was recorded in eight channels [...]
Tape Data Recovery - Videotape
Videotape is a technology that enables recording of images and sound on to a magnetic tape. Video tape is used in video tape recorders and video cameras. Video tape uses helical scan video heads and it records data in two dimensions. Video tape is a linear recording technology, and it is [...]
Tape Data Recovery - Magnetic Tape Sound Recording
Magnetic tape sound recording technology revolutionized radio broadcast and music recording industries. The technology has been popular for more than 75 years. It enabled the radio industry for the first time to pre-record program contents such as advertising, which otherwise had to be presented live. It also enabled [...]
Tape Data Recovery - Digital Compact Cassette
Digital Compact Cassette (DCC) is a magnetic tape sound recording format introduced by Philips and Matsushita in 1992. The product was introduced as the successor to standard analog cassette; however, it did not gain the intended popularity. DCC was discontinued after October 1996.
DCC had the same form factor as [...]
Tape Data Recovery - Digital Audio Tape
Digital Audio Tape (DAT) is a signal recording and playback medium introduced by Sony in the mid 1980s.
DAT technology is similar to that of video recorders. It used a rotating head and helical scan to record data. This prevented the tapes from being physically edited by the cut-and-splice method [...]
Tape Data Recovery - Compact Cassette
A compact cassette, also known as audio cassette or cassette tape, is a magnetic tape sound recording format. Compact cassettes were used in a number of consumer applications ranging from portable audio to home recording to data storage in early microcomputers.
Data Recording Cassettes
One of the first desktop computers to use [...]
Tape Data Recovery - ROM Cartridge
Read-only memory cartridge (ROM cartridge) is a removable cartridge containing read-only memory devices and sometimes a flash memory device that offers read/write functionality. ROM cartridges are commonly used in video game consoles. Example of a ROM cartridge is Game Pak of Nintendo.
The cartridge consists of a printed circuit board that [...]
Tape Data Recovery - Sequential Access
Sequential access, also known as serial access, refers to a process in which data in a memory array, disk file or a tape is accessed in a predetermined and orderly manner.
Magnetic tape storage is a typical example of sequential access memory (SAM). This is because in order to reach a [...]
Tape Data Recovery - Magnetic Tape Data Storage
Magnetic tape data storage is a cost-effective form of data storage. Magnetic tapes have been successfully used for data storage for over 50 years. They are now being used with high-end computers handling large amounts of data, mostly for data backup and archiving. The device that performs the [...]
Tape Data Recovery - Tape Drive
A tape drive is a data storage device that reads and writes data stored on a magnetic tape. Tape drive storage is used to archive data stored on a hard drive.
Tape drives differ from hard disk drives in many aspects. Tape drives only allow sequential access of data while hard [...]
