Claim:
A data recovery method for use with a writable disc system having a writable media, the method comprising: detecting a write disruption in response to a shock event; stopping a first write operation pertaining to a stream of data in response to said shock event, the shock event occurring while the writable disc system is performing the first write operation along a write track; after the stopping, ascertaining, using buffered data, at least a disruption start point and a set of disruption cross-track points, wherein at least the disruption start point, the set of disruption cross-track points, and a disruption stop point define the write disruption; after the ascertaining, determining whether first data of the stream of data written in the first write operation is readable, the first data being written along the write track prior to the disruption start point; if the first data is readable according to the determining, resuming the first write operation starting from the disruption start point along the write track using second data of the stream of data, the second data immediately following the first data in the stream of data; and verifying whether the second data written by the resuming the first write operation is readable from the writable media.
