Abstract: A storage device disclosed herein stores data on a storage media using interlaced magnetic recording (IMR) and it includes a storage controller configured to determine power levels applied to the power source such that power levels applied to heat various tracks can be different from each other. An implementation of the storage device determines the track density, linear densities and power levels for even and odd tracks in IMR HAMR for the storage media.

Abstract: A heat-assisted magnetic recording (HAMR) device includes a controller that selects a power for operating a heat source for a data write to a target data track. According to one implementation, the controller selects the power based on an assessment of whether the target data track is bounded by any data-storing tracks. A first power is selected when the data track is not bounded by any data-storing tracks and a second lower power is selected when the data track is bounded by one or more data-storing tracks. In another implementation, the controller writes to different partitioned regions of a storage media with different powers of the heat source. The controller selects a storage location for data based on an expected write error rate and environmental conditions within the HAMR device.
Abstract translation: 热辅助磁记录（HAMR）装置包括控制器，其选择用于操作热源以用于对目标数据轨道进行数据写入的功率。 根据一个实施方案，控制器基于对目标数据轨道是否由任何数据存储轨道限定的评估来选择功率。 当数据轨道不被任何数据存储轨道限制时，选择第一功率，并且当数据轨道由一个或多个数据存储轨道限定时选择第二较低功率。 在另一实现中，控制器向不同功率的热源的存储介质写入不同的分区。 控制器根据预期的写错误率和HAMR设备内的环境条件选择数据的存储位置。

For example, the transducer head may include two write poles of different width configured to write to a same surface of a storage medium. A controller of the storage device is configured to selectively engage one of the multiple write elements to write data to the storage medium.

Abstract: A storage device controller addresses consecutively-addressed portions of incoming data to consecutive data tracks on a storage medium and writes the consecutively-addressed portions to the consecutive data tracks in a non-consecutive track order. In one implementation, the storage device controller reads the data back from the consecutive data tracks in a consecutive address order in a single sequential read operation.
