Polaroid was a company more famous for its films and instant cameras, but they also lent their brand to a variety of other products. One of them is VHS cassettes – this one dubbed the “HS” for High Standard. Maybe that was a bit of a jab at TDK which also has a line called HS.
The cassettes were unique in shell design – in their ribbing and stamping of the VHS logo.
In fact, the underside ribbing is pretty much exactly as the JVC Excellent Resolution, with the exception that the mould now contains a license number instead (to throw you off).
There is a difference, however – this cassette uses a black plastic roller for the top roller.
