摘要： Some embodiments of the invention are directed to a data storage system that includes a disk and solid-state non-volatile memory (NVM). During a power failure, the data storage system may use back EMF (BEMF) voltage from the spindle motor of the disk to park the heads of the disk and/or store data in the NVM. In one embodiment, a demand regulation circuit regulates loads that use voltage generated from the BEMF. The demand regulation circuit may be used to selectively cause a controller to adjust the rate of programming to the NVM in order to reduce the load. For example, the demand regulation circuit may assert a throttle signal to the controller upon detecting that the voltage generated from the BEMF is below a certain threshold. Programming rate may be throttled, programming cycles may be staggered, and/or programming time may be lengthened. Throttling may enable the use of smaller circuitry.

摘要： A disk drive is disclosed comprising a disk having a plurality of servo sectors defining a plurality of servo tracks that form a plurality of servo zones. The disk drive further comprises a head actuated radially over the disk for generating a read signal, and control circuitry operable to execute a seek operation. A fixed rate clock is generated, and a disk locked clock is generated and synchronized to the servo data rate of the servo zone the head is over. The disk locked clock is used to generate a servo timing window relative to a circumferential location of the head and the servo sectors. The control circuitry seeks the head from the first servo zone to the second servo zone, and switches to the fixed rate clock to generate the servo timing window while the head transitions from the first servo zone to the second servo zone.

摘要： A disk drive comprising a disk, a head actuated over the disk, a read/write channel, a control processor, and a servo system is disclosed. The servo system is configured to read servo information from a servo wedge on the disk via the read/write channel, to generate first and second status information based on the read servo information, to output the first and second status information to the control processor, and to output first and second interrupt signals to the control processor, the first and second interrupt signals being spaced apart by a time delay. In response to the first interrupt signal, the control processor is configured to determine whether to release data from a host based on the first status information, and in response to the second interrupt signal, the control processor is configured to determine whether to release data from the host based on the second status information.

摘要： A disk drive is disclosed having a disk, a head actuated over the disk, a buffer memory for storing control routine op codes and control routine data, and a microprocessor for receiving the control routine op codes and control routine data. Control circuitry within the disk drive services an access request generated by the microprocessor by accessing the buffer memory, and monitors at least one interrupt. If the interrupt occurs while servicing the access request, the control circuitry enables the microprocessor to execute an interrupt service routine corresponding to the interrupt. Enabling the microprocessor to execute the interrupt service routine rather than wait for the access request reduces the latency in servicing the interrupt.

摘要： A disk drive is disclosed comprising a head actuated over a disk having a plurality of tracks, wherein each track comprises a plurality of data sectors and a plurality of servo sectors. The disk drive further comprises control circuitry including a read channel. The control circuitry configures a power mode of the read channel into a no-op mode, and when the head approaches a servo sector, configures the power mode into a servo mode. After configuring the power mode into the servo mode, the control circuitry waits for a pre-servo gate period, and after the pre-servo gate period, enables a servo gate to read the servo sector. After reading the servo sector, the control circuitry disables the servo gate and waits for a post-servo gate period. After the post-servo gate period, the control circuitry configure the power mode into the no-op mode.
