This Mini DV Professional Standard Cassette from Sony is a digital video tape providing up to 63 min of recording time. If your camera supports long play (LP) mode, you can get up to 94 min, though you run the risk of increased errors and drop-outs. The metal evaporated (ME) tape uses a lubricant to reduce friction between itself and the record/playback heads inside the video cassette recorder. Be sure not to mix this Mini DV tape with any other types, as this may cause damage. Frequent cleaning of the record/playback heads in between uses will prevent clogs that can be detrimental to equipment.
