Actually it is very easy to copy a tape. You need an autoreverse head and exact similiar transport mechanisms (called deck). the reader reads both a and b sides simultaneously. The recorder records the same way. You run the tape in cue mode, so that the head is in contact with the tape while it is running at high speed (the head is retracted in ff and rewind). Same for the recording deck. Voila - 60 minutes in 60 secs. These are for small shops. The bigger guys have 1:10. One reader 10 writers. Even bigger guys have synced motors and 1:20x10. 200 copies per minute. Built and sold quite a number of these in the late 70s early 80s. _______________________________________________ network mailing list [email protected] http://lists.fosscom.in/listinfo.cgi/network-fosscom.in
