How Do The 2View Limited Viewing VHS Tapes Work?

batosai writes "I recently read an article about a video cassette that will allow 2 viewings from a pre-recorded source which can them be recorded over and used like a regular video cassette tape. I haven't been able to find anything about how this works. I was hoping someone here might be able to enlighten me." Interesting idea here, and for those that find themselves going thru a lot of video tapes in a month, probably worthwhile. Tapes using this technology are due to hit the Netherlands sometime in May and the indicators point to a possible US release as well although no date is mentioned. An interesting fact from the article: "Introduction of a limited-play cassette has been attempted on several occasions over the past 15 years in the United States without success." What technology was behind those earlier attempts and why did they fail?
