摘要
A data storage device performs a re-read of data prior to a read inhibit for data recovery and validation. When misregistration of read/write heads occurs, as indicated by a sampled servo position, data read from a track of the data storage device is withheld from a host until a subsequent sampled servo position is verified to be within a read limit width of the track. Data blocks preceding the servo position that caused the posting of the read inhibit are re-read, once the read inhibit is cleared. If the read inhibit is not present following the re-read of the data, this re-read data can be released to the host.
