Abstract: A method of forming a recording head for use with a data storage medium in a data storage device. The method includes forming first and second writers of different target geometries. A first recording measurement is performed on one or more storage media using the first writer. A second recording measurement is performed on the one or more storage media using the second writer. Based on a comparison of the first and second recording measurements to a predetermined quantity, either the first writer or the second writer is selected to be operational in the data storage device.

Abstract: Method and apparatus for identifying the track pitch capability of a recording device, such as but not limited to a recording system and/or a servo control system in a data storage device. In accordance with some embodiments, data are written to first and second tracks at an initial track pitch such that the second track at least partially overlaps the first track. Data are arranged on the first track in code words each having a fixed plurality of bits which are decoded as a group by a data channel. The code words are transferred from the first track to the data channel, and a final track pitch for subsequent tracks is responsive to a distance at which nominally half of the code words are undecodeable by the data channel.
Abstract translation: 用于识别记录装置的轨道间距能力的方法和装置，例如但不限于数据存储装置中的记录系统和/或伺服控制系统。 根据一些实施例，以初始轨道间距将数据写入第一和第二轨道，使得第二轨道至少部分地与第一轨道重叠。 数据以代码字排列在每个具有由数据通道解码为组的固定多个位的码字中。 代码字从第一轨道传送到数据通道，后续轨道的最终轨道间距响应于数字通道的代码字的名义上一半是不可解码的距离。
