Abstract: The disclosure is directed to a system and method for interleaving data utilizing a random access buffer that includes a plurality of independently accessible memory slots. The random access buffer is configured to store slices of incoming data sectors in free memory slots, where a free memory slot is identified by a status flag associated with a logical address of the free memory slot.

Media sectors including the interleaved data slices are read out from the memory slots of the random access buffer in order of the sequence of labels stored by the label buffer. As the media sectors are read out of the random access buffer, the corresponding memory slots are freed up for incoming slices of the next super-sector.
