Sony DAT audio DTC 690 drum assembly/ DOU-03A/ 8-848-567-11
Initially, anyone know how to get the top drum off, I don't want to heat
up to separate interference fit , if there is some secret fixing.
Then anyone happen to know if video heads are the same, they look the same
via what little I can see of them.



Video heads are a damn sight bigger than DAT heads, but the principle of
operation is exactly the same.
Some portable DAT players used an even smaller head, but you had to wrap
more than 90 degrees of tape around it to compensate, not good in terms of
tape friction/tension etc.

I used to fix a lot of DAT's, but never once felt inclined to take a head
apart.



Cheers,

Gareth.
