An approach to self-servo writing (SSW) in a hard disk drive involves receiving a first signal from a first reader reading from a first disk media surface while concurrently receiving a second signal from a second reader reading from a second disk media surface, where the relative position of the first and second readers is determinable based on the first and second signals. For example, the first signal may correspond to the SSW reference head while the second signal may correspond to any one of the other SSW non-reference heads, during a SSW bank writing procedure, whereby the relative position and/or motion between the reference and non-reference heads can have a deleterious effect on the servo track writing quality. Because multiple different non-reference heads may be selected for signal reception and associated position determination, the first and second disk media surfaces may be constituent to different disks. |
