Is transition logging a viable option for a transaction log?

When I read about logging techniques, sometimes in the passing by 'transition logging' is mentioned. I specifically mean the method of XORing old value and difference to get new value etc.

Is this method in use anywhere or is it just a pipe dream given the increased need to read from disk to UNDO/REDO a value?

Thanks
