Abstract
A method for media disaster recovery when recording data to re-writable disk media can include defining a sequence of recordable units (RUs) in the re-writable disk media wherein each RU in the sequence has a maximum data capacity. Data can be sequentially recorded in each RU, in sequence. When data has been completely recorded in an RU, RU metrics can be computed. Subsequently, the computed RU metrics can be stored in an RU information file in the re-writable disk media. Significantly, responsive to a media disaster, for example a power outage, a disaster RU can be identified in the RU information file. Specifically, the disaster RU can be an RU in which data had been incompletely recorded during the media disaster. Upon identifying the disaster RU, the sequential recording of data can resume in an RU next in sequence to the disaster RU.
