For users who prefer to have a device do most of the work, PlusDeck may be the ideal solution for converting old cassette tapes into digital audio tracks. Instead of connecting a traditional cassette deck to your PC sound card, this tape deck fits in a 5.25-inch drive bay, just like the ones designed for CD and DVD hardware. If archiving tapes in digital format doesn't interest you, the deck works just as well for playing cassettes over your PC speakers.
Do you shoot videos with a camera or camcorder?
