ABSTRACT:
Various embodiments for writing data in a tape medium having wraps by a tape drive are provided. The tape drive allocates the wraps in a shingled data band between two or more data partitions. A set of contiguous wraps is allocated to one data partition of the two or more data partitions. An additional set of contiguous wraps is allocated to an additional data partition of the two or more data partitions. A minimum buffer is retained between the set and the additional set of contiguous wraps of at least one wrap per direction written within at least one data band shared between the one and the additional data partitions such that the one and the additional data partitions may be written to by the tape drive independently of each other.
