Abstract: Systems and methods are disclosed for detecting shingled overwrite errors. When a read error is encountered when reading from shingled recording tracks, a processor may determine whether the read error is an error caused by shingled overwriting. The processor may determine whether the read error is caused by shingled overwriting by determining read signal quality of one or more sectors preceding the read error, such as based on a bit error count or bit error ratio (BER), and comparing the read signal quality to a threshold value. The processor may determine that the read error is caused by shingled overwriting when the read signal quality value is lower than the threshold.

Abstract: A method includes receiving at a storage device a command from a host. When learning is active on the storage device, an initial parameter value of a plurality of parameter values is used for performing a first action of a plurality of actions for the command. The first action is performed using the initial parameter value of the plurality of parameter values for the command The first parameter value is incremented to a next parameter value of the plurality of parameter values for the command for use in reperforming the first action.

Abstract: A method includes storing a data group in a first zone of a plurality of radial zones of a data storage disc. Each different one of the plurality of zones has a different throughput level. The method further includes obtaining information related to an access frequency of the data group stored in the first zone of the plurality of zones. Based on the information related to the access frequency of the data group and the different throughput levels of the different zones, a determination is made as to whether to migrate the data group from the first zone of the plurality of zones to a second zone of the plurality of zones.

Abstract translation: 公开了用于检测带状覆盖错误的系统和方法。 当读取带有空白的记录轨道时出现读取错误时，处理器可以确定读取错误是否是由遮盖重写引起的错误。 处理器可以通过例如基于比特错误计数或比特误码率（BER）来确定读取错误是由通过确定读取错误之前的一个或多个扇区的读取信号质量的带状重写引起的，以及比较读取信号质量 达到阈值。 当读取信号质量值低于阈值时，处理器可以确定读取错误是由带状重写引起的。
