ArVid (Archiver on Video) (Russian: АрВид, Архиватор
на Видео) is a data backup solution using a
VHS tape as a
storage medium. It was very popular in
Russia and former USSR in
It was produced in Zelenograd,
Russia by PO KSI.

VHS tapes and recording units for data backup.
Hamming code error correction
Easy data copying between two
VHS units (eliminating need of a
computer for data copying)
Inefficient tape capacity usage (only 2 grades of luminance signal
spectrum were used)
Poor software support
VHS recorder unit should be connected to an
ArVid ISA board via a
composite video cable. Unit operation is controlled by a remote
control emulator using an LED.
Device may operate in two modes: low data rate at 200 kbyte/s and high
data rate at 325 kbyte/s (equivalent to roughly 1.33x and 2.17x CDR
recording speed). The original, lower recording speed was retained as
a user option because not all
VHS recorders of the time offered
sufficient recording quality to reliably support this higher speed.
An E-180 video tape is able to hold 2 GB of uncompressed data at the
lower rate, more than sufficient for most PC hard drives of the time.
This can be shown by calculating 200 KB x 60 x 60 x 3 = 2.06 GB (2.06
x 2^30 bytes), which also leaves a few minutes spare for header and
Note that it is unclear here whether "200 kbyte" means 200,000 (200 x
10^3) or 204,800 (200 x 2^10); the above calculation assumes the
latter, but the former still produces a capacity of 2.01 GB (2.01 x
2^30 bytes), providing 2.00 GB of capacity in a little under 2 hours
and 59 minutes. Similarly, this means an E240 4-hour tape, using the
higher data rate, would be capable of storing between 4.35 and 4.46 GB
(2^30 bytes), approximately equivalent to a standard single-layer
ArVid 1010 was first of
ArVid devices. Its production started in 1992.
ArVid 1020 was a successor to
ArVid 1010 using more advanced
ArVid 1030/1031 had better internal design, less power consumption,
was less in size and was made using CPLD. It allowed automatic
switching to a TV set when device was not in use.
ArVid 1051/1052 introduced 325 kbyte/s data rate and 128/512 kbyte
buffer cache (respectively).
