摘要： Systems and methods for maximizing shingled magnetic recording (SMR) drive capacity are described. In one embodiment, the SMR drive may include a main store to store user-accessible data, a media cache and media scratchpad to store internal data temporarily for internal operations, and a storage controller to process read and write requests. In some cases, the main store comprises a shingled media partition and an unshingled media partition. The storage controller may designate one or more data tracks from the shingled media partition as temporary data track guard bands. In some embodiments, a track range is selected based at least in part on at least one of an amount of data in the media cache, a size of the new data in the media cache, and an association between the new data in the media cache and data currently stored within the selected track range.

摘要： Address information that has been error correction encoded is recorded on a second version of a recording medium after being transformed such that such that the address decoding cannot be performed by a playback device that is not compatible with the second version of the recording medium. The address decoding for the second version of the recording medium cannot be performed by the incompatible playback device (for example, a playback device that was manufactured to be compatible only with a first version of the recording medium). In other words, in the playback device that is not compatible with the second version of the recording medium, a state is created in which address errors cannot be corrected, so access is impossible (recording and playback are impossible).

摘要： An information recording medium includes a lead-in area, a user data area, and a lead-out area, wherein at least one of the lead-in or lead-out areas includes a compatibility information area in which compatibility information, specifying whether each area on the information recording medium is recordable and/or reproducible. The compatibility information may include state information on whether the user data area is recordable and/or reproducible, state information on whether the lead-in/lead-out area is recordable and/or reproducible, state information on whether the compatibility information area is recordable and/or reproducible, or state information on whether a defect management area (DMA) is recordable and/or reproducible. Accordingly, an existing drive or apparatus for recording and/or reproducing data on and/or from an information recording medium can smoothly record and/or reproduce data on an information recording medium that is of a higher version than the existing drive or apparatus.
