Abstract:
1. A disk drive detection system for detecting rapid off track events occurring in a disk drive, said system comprising: an actuator assembly including a microactuator, said actuator assembly being movable with respect to a disk of the disk drive for writing data to and reading data from respective tracks on the disk, said microactuator including at least one piezoelectric element producing a voltage signal in response to a rapid off track event; a detection circuit for detecting an off track event, said detection circuit analyzing the voltage signal produced from said piezoelectric element and comprising: means for remediating an error condition caused by the rapid off track event, said means for remediating including at least one of a software or firmware application incorporated in said disk drive wherein a drive mode of said disk drive is analyzed for read/write errors caused by said rapid off track event.
