Channel Gateway (CGX) [5] is mainframe virtual tape controller software and hardware (together, an "MVT controller") that provides mainframe access to disk-based open systems storage by acting as tape control units and presenting the storage as "virtual" tape drives (emulating IBM 3490/3590) via FICON or ESCON channels.
Usually, an interface module, such as the Casio FA-1, was used to connect the calculator to an ordinary cassette recorder, and digital data were encoded as frequency-shift keyed audio signals. [10] Sharp and Hewlett-Packard also sold dedicated micro-or mini-cassette recorders that connected directly to the calculator. These set-ups, while being ...
This was later replaced by magnetic tape recording. While reel-to-reel tape was used for dictation, the inconvenience of threading tape spools led to development of more convenient formats, notably the Compact Cassette , Mini-Cassette , and Microcassette .
The Recorder has mono sound output from a built in speaker on the top of the unit. A convenient volume control is accessible on the left hand side.

From 1963 to 1970, Ampex manufactured several models of VTR 2-inch helical VTRs, capable of recording and playing back analog black and white video.

One video drum rotation time was ...

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).
