call a subroutine when the beginning of record is seen

It may work if the first and last ~~record~~line are supposed to be processed by the sub, but what if the final line is supposed to be processed by some other piece of code? You can't just ungetc a readline...

Also, note that your process_record is making use of a global variable, DATA, and three of your four examples will throw an undef warning if the end-of-file is reached before the closing line is seen.

I think a state machine type approach would be better, because it is more flexible and can handle the above cases specially, if needed.
