Disclosed herein are aspects of optical tape technology. A segment (1210) on media (1110) includes tracks (1220) with length (1230). Segments (1210) may be separated by gaps/defects (1310). Within segment (1210), tracks (1220) each exhibit fields of modulated wobble indicative of a physical track address. Tracks (1220) may not line up across gaps (1310). While focused on a particular track and prior to encountering the first gap, servo system (1150) may record the specified physical address of the particular track. Once gap (1310) has passed the optical sensing element (1120), servo system (1150) may command sensing element (1120) to refocus and determine/record the physical track address of the post-gap track it is focused on. Servo system (1150) may then assign a single logical address to the recorded physical addresses. |
