What is Betacam SP?
Each cassette comes in two sizes: S and L. Betacam cameras only load S tapes whilst the VTRs can play both S and L tapes. The cassette shell and case for each Betacam cassette is coloured differently depending on the format allowing for easy visual identification.
The original Betacam
format records on cassettes loaded with oxide-formulated tape, which were
to all intents and purposes theoretically the same as used by its consumer
market-oriented predecessor Betamax. A blank Betamax-branded tape will
work on a Betacam deck and a Betacam-branded tape can be used to record
in a Betamax deck but this practice was discoraged by Sony.
