SONY U-MATIC VIDEO CASSETTE RECORDER MODEL VO-1810, 1970's

The worlds first Video Cassette Recorder (VCR) was the Sony VP1100 launched in 1971, using Sony's new U-Matic Cassette ('U' indicates the way it wraps round the head drum), this was prior to Betamax or VHS types which would come later, this first machine, the VP1100, was playback only it could not record. It was however designed for the domestic market, having wooden sides to the cabinet and playing pre-recorded tapes, just like today’s DVD's, this model was eventually replaced by the machine in our picture, the Vo-1810 which had recording capability but no internal TV tuner which was available later. Again designed for the domestic market, but at around £600 pounds sterling few could afford it, the machines would also be used by professional companies using a separately purchased video camera. The unit is over 600mm wide and weighs over 35Kg.

KYOTO S600 8 TRACK STEREO PLAYER, 1980's

The original format for magnetic tape sound reproduction was reel-to-reel audio tape recording, first made widely available in the late 1940s. However, threading tape into the recorders was more difficult than simply putting a disc record onto a phonograph player. Manufacturers introduced a succession of cartridges which held the tape inside a metal or plastic housing to eliminate handling. The first was RCA Victor, which in 1958 introduced a cartridge system called Sound Tape or Magazine Cartridge Loading, but until the introduction of the Compact Cassette in 1963 and Stereo 8 in 1965, none were very successful.

AGAPHONE WIRE RECORDER, 1950's

Wire recorders were invented in Denmark by Valdimar Poulson for an answering machine in 1898 called a Telegraphone, but were not developed for any other practical purpose at the time. Ten years later a company in America made a successful dictation machine. They were quickly made obsolete by magnetic tape machines.

Although this machine carries the trade name Agaphone, this unit was certainly made by another company

WEBSTER CHICAGO WIRE RECORDER MODEL 180-1 of 1949

Formed in 1914 the Webster Electrical Corp specialised in consumer Audio products up until the 1960's. The Chicago Model 180-1 Electronic Memory wire recorder of 1949 used 0.0036-inch Stainless steel wire travelling at 24 inches per second past a head moving vertically to spread the wire evenly on to the take up spool. The Quality on some models was exceptionally good. In 1952 Webster started production on tape machines, and also started using the trade name Webcor.

BOOSEY & HAWKS WIREK TYPE 'A' WIRE RECORDER , 1945

Boosey and Hawkes stopped making machines and only produced sheet music after this model.
Valdemar Poulsen, a Danish inventor developed the "Telegraphone" between 1898 -1900 this was a magnetic method using steel wire
Wire recorders were developed in the period from 1900 to the late 1940s, but they were produced only in very small quantities.
They were used by BBC journalists during WWII.
The peak of the wire recorder's short commercial life came in 1948 and 1949.

FERROGRAPH SERIES 6 REEL TO REEL TAPE RECORDER, 1960's

The Ferrograph was semi professional machine seen many times in films and used by the BBC.

This version of the Series 6 is a half track stereo machine with 8.25 inch reels and using standard 1/4 inch tape. A quarter track version was available. It had three motors, two used for fast forward, rewind and back tension and one, a split phase capacitor induction motor, for the flywheel and capstan. This type of motor is almost immune to small variations in voltage or load and is controlled by the mains frequency after reaching its synchronous speed. Three speeds were provided 7.5, 3.75, and 1.125 inches/second. It was extremely heavy using valve amplification and built on a sturdy frame.

The companies Wright and Weare first produced machines in the late forties and eventually introduced the famous Wearite deck seen here
