Seems like the A10 might benefit from the hold system on the Zoom F1. On that, there's a menu option to turn on the "record hold" feature. Once that is engaged, when it is recording there is absolutely no way to stop it (not even turning off power) unless you press "stop" and "rec" at the same time. And the record button has a ring found it so it is fairly hard to press in accidentally, let alone with the stop button pressed as well. For all I know that may be an option on other devices, but apparently not the A10.
