Some drives will back up, get up to speed, read the end of the previous
block, switch from write to read when the irg goes by.
I think they all back up and then start accelerating. But how precise
can you make the acceleration? And how fast can you switch from read to
write? All drives I've worked on created long gaps if they appended a
new block from standstill.
The size of the irg can vary upwards from a minimum spec, at least in
drives that try to stream, as they will keep the tape running for a
moment in hopes that data will arrive to be written.
Yes.
