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 ...
Modern tape drives offer a speed matching feature, where the drive can dynamically decrease the physical tape speed as needed to avoid shoe-shining. [ 23 ] In the past, the size of the inter-block gap was constant, while the size of the data block was based on host block size, affecting tape capacity – for example, on count key data storage.
There are at least four main models of the 1530/C2N Datassette: The original modified Sanyo M1540A cassette drive, built into the earliest models of PET in 1977. This was a standard shoebox tape recorder with a corner of the case removed and modified electronics; a Commodore PCB was installed internally in place of the Sanyo electronics.
In addition to the standard packet format, the driver gives the user direct control over the tape drive motors and reading and writing the tones. This is used with audio tapes to control playback. A typical scenario has an audio recording on the "left" track and short bursts of 5327 Hz at key locations within the audio.
Each tape is a continuous loop, unlike cassette tape. It was intended to compete with Sinclair's ZX Interface 1 and ZX Microdrive. The Wafadrive comprises two continuous loop stringy floppy tape drives, an RS-232 interface and Centronics parallel port. The drives can run at two speeds: High speed (for seeking) and low speed (for reading/writing ...
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.
So a tape written in the H drive can only be read in an H drive. A tape written in an E drive can be read in an E drive and an H drive. A tape written in a B drive can be read in a B, E or H drive. Unlike DLT, LTO or 3592 drive variants, the 3590 drive is not capable of writing at a lower density than its native density. There is often ...
At the end of the tape, the drive reversed the direction of tape motion, moved the read and write heads slightly vertically across the tape, and continued to write (or read) more data until the beginning of the tape was reached. This process could be repeated many times, laying down several track sets on the tape media in a serpentine recording ...
