Tapes are known for wasting 20 minutes only to find out that the load screwed up because the magnetic tape is not that reliable due to parasistic noises.
A problem encountered with this standard lies when the software have to take control of the Datacorder (to stop or play...)
Any AudioTape was far cheaper than a 3" disk, and easier to find.
You could get 90 "minutes " of Datas, compilations were fun to make.
Also you could copy any games with any audio double tape system.
Yet some games still include Copy protections...
==Modern use== The use of Audio signal was clearly improved recently as modern Audio devices are not more analogic by logical. As said, less parasitic noises and reliable durable storage. Bad quality magnetic tapes had to read slowler to compensate the poor sound. Clean modern logic signal allows to read at faster speed. Yet the silence times between each blocks must remain of 3-4 seconds (this is the uncompressible part...). ==The strange case of the 6128+==
Oddly, the 6128+ does not have any Tape connector at all.
