Akai Glass Head Tape decks are Garbage watch and find out why

There is much controversy about the glass heads that Akai put on many tape decks in the 80's. Some swear by them, meanwhile many more swear at them. Glass heads amplify the sticky shed tape problem that plagued millions of old tapes. Musicians know how bad they are and most won't let their old tapes anywhere near them. The problem is the head is so smooth that the tape sticks to the head and it starts to scrape the oxide off.
See for yourself, a tape is played on 2 Akai glass head recorders and will not play, and is also placed on a conventional metal head recorder and plays without problems. You want proof that the glass heads are problematic, well lets see you dispute this unscientific test.
