Abstract: A data storage device can employ shingled magnetic recording with data tracks oriented in order to optimize operational parameters, such as bit error rate. A data storage device can consist of a plurality of data tracks overlapping in a band on a data storage medium. First, second, and third data tracks of the band can be respectively separated by a uniform first track pitch during testing the band for an operational parameter. The first track pitch may then be adjusted to provide at least two different adjusted track pitches with each track pitch measured between longitudinal centerlines of adjacent data tracks of the band.

Abstract: Embodiments described herein are operable with a storage device. In one embodiment, a method provides for buffering first portions of incoming sequential data from a plurality of channels in a buffer, and identifying locations of the storage device to store the first portions of the incoming sequential data. The method also provides for directly writing the first portions of the incoming sequential data from the buffer to the identified locations of the storage device.
