CV 2000 ½” open reel Videocorder decks

The CV 2000 was announced by Sony in Japan in October 1964. It was a 2-rotary head  unit which used a half-inch tape, and was intended for the consumer market.

According to the SONY website, in 1964, a team led by Nobutoshi Kihara developed the CV-2000, which was marketed in 1965.  These Videocorder decks, when used with a Sony receiver/ monitor record both the video and audio portion of any off-the-air TV channel on half-inch video tape. With the Sony TV camera (or any similarly designed camera) these decks will record "live" action. They can play back the recorded material through a monitor or TV receiver in both sight and sound.

 There are two Sony decks with the same electrical and mechanical capabilities throughout. Both provide the basis of a TV recording studio for business or educational application. They employ the ingenious Sony alternate-field scan and repeat-field playback system, making it possible to operate the tape at a slow 7 1/2 ips. An hour of program material can be recorded on a 7-inch reel. Cost is less than $40, and the tape can be erased and used again and again.

 Model CV-2000. The most portable video tape recorder ever designed, is housed in a sturdily-constructed carrying case with a durable leatherette finish. Weighing only 46 lbs., it can be carried easily from location to location.

 Model CV-2000D. This economical deck is housed in a handsome walnut-finish case. Compact, it can be installed anywhere—even where space is limited.

 These compact, lightweight decks make possible a wide range of applications. Using a Sony monitor and the VCK-2000 Sony Video Camera Ensemble (TV camera, tripod and microphone) "live" indoor and outdoor scenes—both sight and sound—can be recorded and played back instantly or stored for future use. This opens the way to a wide variety of applications in education, science and business for sales training, production training, surveillance, continuous monitoring of hazardous operations, dramatic and athletic instruction etc.

These decks are designed for use with the Sony receiver/monitors, the large-screen CVM-2300U or the port-able CVM-51UWP. Used with a branch cord, the Videocorder decks can be connected to more than one monitor, an important feature for large group presentations. The Sony TV Adapter makes it possible to employ standard TV receivers for off-the-air recording or playback.

 
An important feature of these units is tape interchange-ability. Any tape recorded on one Sony Videocorder can be played back on any other Sony Videocorder. For ex-ample, a recording made at company headquarters can be distributed to any division or branch where a Videocorder is available. Similarly, educational institutions can exchange tapes with other schools.
