As far as the length of recording, it depends on how the individual jet is configured (don't ask me why-- jets from the same series can have different recording lengths). Some are 30 minutes, a few are 25 hours. This one was 120 minutes and they're automatically overwritten.

ah, yes, I must admit I didn’t think about the recording from the ATC.
