Claim:
A method of managing a plurality of data storage media, each of said media being designatable as being in a writeable state or a non-writeable state, said method comprising: designating a quantity of said plurality of media as being in the writeable state, said quantity being equal to a concurrency value; determining that none of the media designated in the writeable state has sufficient space to store specified data; designating an additional one of said plurality of media as being in the writeable state whereby the aggregate number of media in the writeable state exceeds said concurrency value; and writing said specified data to the additional medium, wherein said plurality of media comprise double-sided media, each side of the double-sided media being separately designatable as being in a writeable state or a non-writeable state, and wherein said determining act comprises: determining that no side of said plurality of media is in the writeable state and has sufficient space to store said specified data; and wherein said designating act comprises: identifying one of said double-sided media having a first side in the non-writeable state and having a second side whose state has not been designated; and designating said second side as being in the writeable state.
