20170140783 | VIRTUAL WINDOW MODE FOR GUIDE SPIRAL SERVO DEMODULATION - A write head is positioned over a disk surface of a hard disk drive during a self-servo write process. A virtual window mode is employed for positioning the write head, in which the read channel of the hard disk drive continuously searches for servo spirals, but spiral detection is disabled except during specific time intervals, or “virtual windows.” Each virtual window is associated with one specific servo spiral on the disk surface, and has a predetermined duration. The duration and timing of these virtual windows may be selected to ensure that spiral detection is enabled while a read head of the hard disk drive passes over the associated servo spiral, even when servo spiral placement is not ideal. | 2017-05-18 |
