It's a big challenge when a customer sends you over 100 tapes to transfer! To get the best results during the transfer process you need to fast-forward all of the tapes. This allows any loose debris to fall off the tape. Another benefit is that signs of "sticky shed" syndrome will show up during the fast-forward & rewind processes.
The problem is that using your AG1980 to fast-forward and rewind tapes is a very time consuming procedure (it also contributes to video head and tape path wear). Using your AG1980 to check tapes this way, ties it up and keeps it from it's main function of playing back tapes!
There's a serendipitous answer to the problem!! Use a lower priced high-speed fast-forward VCR. These have modern mechanisms that slowly ramp up the fast-forward speed to an extremely high speed, As the tape nears the end of the cassette, the mechanism slows down, then for the last 20ft or so, it crawls. So there's no chance of snapping off the end of the tape! During our tests, our refurbished Curtis Mathes VCRs fast-forwarded (or rewound) a full T-120 cassette in only 60 seconds! T-160 cassettes take only 90 seconds! Quite amazing! So while your AG1980 is occupied as the playback source for your digital transfers, you can be checking other tapes on the "high-speed" VCR. It's a real timesaver! ~ Tom G.
