Mon, 2 Apr 2007 16:00:00 GMT http://www.tapesuk.co.uk/acatalog/Video.html Video Tape is a method for recording moving images and sound onto magnetic tape and replaced Film as the consumer standard for home recording systems. The recording systems works by having a helical scan video head rotating against the moving video tape in order to record the data in two separate dimensions. As video signals have a high bandwidth static heads would require high video tape speeds. Both VTRs (video tape recorders) and VCRs (video cassette recorders) use the video tape format. The disadvantage with video tape as a recording medium is that is uses a linear format, meaning that newer digital recording media provide better quality than video tape.

You can also purchase 80 minutes tapes using a thinner tape, and they can record 120 minutes of footage in either EP or LP mode. Using a home PC you can record computer data directly on your Mini DV tape using a camcorder. Using a 60 minutes Mini DV cassette you can store 13 GB of data. Mini DV L-size cassettes were originally intended for consumers as a replacement for Blank VHS tapes, yet are now mostly used by professionals in video production.

As a result DVCAM has a higher track width of 15 micrometres. DVCAM uses the same codec as normal DV so the chance of dropout errors with DVCAM is greatly reduced. DVCAM doesn't allow the same LP mode that regular DV has.

Blank VHS became the standard format for consumers by the late 1990s after beating off competition from Sony's Betamax system. One of the contributing factors to its success was that blank VHS tapes offered a longer recording time than their Betamax counterparts. Blank VHS also had the advantage of a less complex tape mechanism which allowed home users to rewind and fast forward their blank VHS tapes much faster than any Betamax VCR could manage.

Digital Beta costs significantly less than the D1 format and provides quality and reliability. Digital Beta S tapes come with up to 40 minutes running time, whereas the L tapes have up to 124 minutes. The Digital Beta records a DCT-compressed component video signal. Digital Beta also has a 5th analogue audio track which is used for cueing, plus it has a linear timecode track. Digital Beta equipment is the professional standard in digital video production, and is far superior than cheaper digital formats, such as DVCAM and DVCPRO. Digital Beta is usually found in a blue cassette container. Mon, 2 Apr 2007 16:00:00 GMT
