JVC HR-3300U VIDSTAR - the United States version of the JVC HR-3300. It is virtually identical to the Japan version. Japan's version showed the "Victor" name, and didn't use the "VIDSTAR" name.

The JVC HR-3300 (also known as the Victor HR-3300) is a VHS-based video cassette recorder (VCR). It is the world's first VHS-based VCR to be released to the market, and was introduced by the president of JVC at the Okura Hotel on September 9, 1976.[1][2] JVC started selling the HR-3300 in Akihabara, Tokyo, Japan on October 31, 1976.[1] Region-specific versions of the JVC HR-3300 were also distributed later on, such as the HR-3300U in the United States, and HR-3300EK in the United Kingdom.

In 2008, the HR-3300 became the first VCR to be registered with the National Museum of Nature and Science, based in Tokyo, Japan.[3]

History[edit]

The JVC HR-3300 was a result of years of development - much of it in secret from JVC executives. JVC engineers Yuma Shiraishi and Shizuo Takano led the effort in developing the VHS tape format in 1971.[4] The project started off by designing guidelines for VHS, creating a matrix on a blackboard called the VHS Development Matrix. Included in the matrix is a list of objectives in building a home video recording unit.[5] The HR-3300 is a result of these objectives.

Soon after the Matrix was produced, the commercial video recording industry in Japan took a financial hit. As a result, JVC cut its budgets and restructured its video division - even going as far as shelving the VHS project. However, despite the lack of funding for the VHS project, Takano and Shiraishi continued to work on the project in secrecy within the video division. By 1973, the two engineers successfully produced a functional prototype of the HR-3300.[5]

The HR-3300 is JVC's initial release of its VHS technology. Other manufacturers took the JVC open standard and developed their own products.

Specifications[edit]

Inside the JVC HR-3300U.

Being the very first VHS-based VCR, the HR-3300 is the result of the VHS Development Matrix in terms of ease of servicing. This is the only JVC-manufactured VCR that did not use any integrated circuits or miniaturized parts. Literally, the parts in this VCR can be purchased at any electronics parts store. Virtually all of the parts that make up this VCR are still available today.
