Omega Wrap

Omega tape wrap system which takes up a lot less space than a conventional Betamax deck. Omega wrap reduces the size of the video head drum by employing a second set of video heads which are used to record alternate frames of picture information. This was later to be adopted in camcorders of other formats.

Superior Picture Quality

A second thing to note is that the Chroma and Luminance video information is at no point within the BMC-100 combined as composite video. This means that the BMC-100 was able to treat colour and luminance information separately which resulted in superior picture quality.
