Abstract: A storage device includes a storage controller configured to write a band of data tracks using a first recording method until criterion is met. The first method may be a conventional recording method. After the criterion is met, the storage controller is configured to write data to the band using a second recording method. The second recording method may be an enhanced capacity recording method such as interlaced magnetic recording (IMR) or shingled magnetic recording (SMR).
Abstract translation: 存储装置包括存储控制器，该存储控制器被配置为使用第一记录方法写入数据轨道带，直到满足标准。 第一种方法可以是常规记录方法。 在满足标准之后，存储控制器被配置为使用第二记录方法将数据写入频带。 第二记录方法可以是诸如隔行磁记录（IMR）或带状磁记录（SMR）的增强容量记录方法。

Abstract: A storage device includes a storage medium and a storage device controller that selectively varies a value of at least one write current parameter to generate alternating data tracks of variable written track width. According to one implementation, the alternating data tracks of variable written track width are generated with a single writer.
