Briefly described, one embodiment of a method of recording data in a sequence of data sets onto a data recording medium having a recording capacity up to an end of medium position includes the following steps: deriving a logical count of the amount of data recorded on the recording medium, and comparing the logical count to a reference value to generate a warning of an approach to the end of medium position. Other methods and systems are also provided.
