ABSTRACT:
Data recovery methods for use with a writable disc system having a writable media are presented including: detecting a write disruption in response to a shock event, the write disruption being defined by a disruption start point, a portion of off-track writing which may include a set of disruption cross-track points that contains at least one disruption cross-track point, and a disruption stop point; stopping a first write operation pertaining to a stream of data in response to a detected shock event, the shock event occurring while the writable disc system is performing the first write operation along a write track; determining whether a first data of the stream of data written in the first write operation located in the region of write disruption is readable; and if the first data is readable, resuming the first write operation.
