Appeal No. 2006-2321 Application No. 10/706,254 The disclosed invention relates to the self-servo writing of a hard disk drive (HDD) in which write control bits are associated with servo pattern data bits to selectively disable or enable a write gate in a HDD write channel, the write gate being disabled or enabled without deenergizing the write channel. More particularly, from one timing mark to the next, a single write delay is calculated which enables the writing of the next timing mark and portions of the radial pattern and servo pattern between the timing marks. Claim 1 is illustrative of the invention and reads as follows: 1. A HDD, comprising: at least one write channel including at least one write gate; and control circuitry encoding write control bits for controlling the write gate to selectively enable writing data bits associated with a servo pattern onto at least one disk. The Examiner relies on the following prior art: Hussein 6,285,521 Sep. 04, 2001 Bryant et al.
