Now we are really getting into the hi-tech part of this. Actually, cassette tape is too light and dances too much to read properly. Sort of flitters around while it should be settling down and doing a good job.
That is why I use the heavier, 8-Track Tape. But, if you can't find 8-Track anymore, you can buy some reel-to-reel tape at Radio Shack. Tim Johnson told me they are both 1.25, or something like that.
But I still like my 8-Track.
Using some really fast stuff now: Abba
