摘要： According to one embodiment, a disk storage apparatus includes a write module and a controller. The write module is configured to move a write head over a disk, and to perform the shingled write method, recording data in the first track while erasing data from a part of the second, i.e., adjacent track. The controller is configured to acquire a first head positioning error with respect to the first track and a second head positioning error with respect to the second track. If the first head positioning error exceeds an off-track threshold value, indicating that the data may no longer be maintained in the first and second tracks, the controller inhibits the data writing.

摘要： A method and apparatus for generating a laser signal for driving a laser used in thermal-assisted recording. A channel of a hard drive generates a high-frequency component of the laser signal—e.g., a periodic wave or series of pulses—and synchronizes the phase of the laser signal with a corresponding write data signal which controls the magnetization of data bits within the magnetic disk of the hard drive. The channel may be connected to a read/write integrated circuit via a channel interconnect. The read/write circuit may include a second phase control to compensate for any phase shift and an adder circuit to combine the transmitted high-frequency laser with a DC bias. Further, the read/write circuit may include a feedback loop for adjusting the DC bias based on environmental parameters of the hard drive such as temperature.

摘要： A disk drive is disclosed wherein a plurality of access commands received from a host are stored in a command queue. An access cost for at least a first and second access command in the command queue is generated, wherein each access cost comprises a seek length and a rotation latency. A first access command is selected from the command queue having a first access cost, and a window is defined relative to the first access cost and a first risk based penalty (RBP) of the first access command, wherein the first RBP represents a probability of missing a first data sector of the first access command. A second access command is selected from the command queue comprising a second access cost within the window. A choice is made between the first and second access commands in response to a second RBP of the second access command.
