摘要： Embodiments of the present invention include a method and an apparatus for generating an optimal MRO for a zone having a plurality of tracks. A disc drive controller determines the optimum MRO of a zone of tracks by analyzing multiple tracks in the zone with the actuator arm located at a series of offsets relative to the track center. Selected tracks in the zone are written to once. Then the selected tracks in the zone are sequentially read at a first offset, and the corresponding errors recorded. This reading is repeated for each of the offsets until all offsets have been analyzed. Based on the offset, or band of offsets, with the least errors over the selected tracks, the optimum MRO can be selected for the zone. The process can be repeated for each zone and the optimum MRO values stored in an MRO table in the disc drive for use during subsequent read and write operations.

摘要： A reader-to-writer offset for a head positioned over a track on a disc in a disc drive having a plurality of tracks is generated by using two iterations. A first iteration is used to determine a fine-tuning range that is used for a second iteration. The first iteration uses coarse steps of the reader across the track pitch to roughly determine OTC boundaries (which are used as the fine-tuning range). The fine-tuning range is determined by locating the point before the first valid reading (e.g., a VGA reading or BER reading with a rate that is less than the BER threshold) and by locating the point after the last valid reading. The second iteration uses fine steps of the reader across the track pitch to determine the actual OTC boundaries. The OTC boundaries are the first valid reading and the last valid reading that are made using the fine steps.
摘要翻译：通过使用两次迭代来生成具有位于具有多个轨道的盘驱动器中的盘上的轨道上的头的读写器偏移量。第一次迭代用于确定用于第二次迭代的微调范围。第一次迭代使用阅读器在轨道间距的粗略步骤粗略地确定OTC边界（用作微调范围）。通过在第一次有效读取之前定位点（例如，具有小于BER阈值的速率的VGA读数或BER读数）以及通过在最后一次有效读数之后定位点来确定微调范围。第二次迭代使用读者跨越轨道间距的精细步骤来确定实际的OTC边界。 OTC边界是使用精细步骤进行的第一个有效读数和最后一个有效读数。
