摘要： A hard disk drive for a computer system has at least two actuators for reading data from or writing data to the disks. The actuators may be configured to support the different methods of data access required of them. For example, if large quantities of sequential data are performed, one operation uses both actuators to increase throughput. However, if mostly random operations are to be performed, then independent usage of the actuators is preferred. These two methods of usage can be supported simultaneously, and can even be dictated by the user. The tracking format of the actuators can be configured such that the next logical track is physically located under a head on a different actuator to improve sequential operation. The actuators also may be utilized in a dual-channel configuration so that data can be written to both actuators at the same time, or read back at the same time to improve throughput. In addition, either of these configurations can be selected on a transfer-by-transfer basis by the user.

摘要： A system and method for precompensating for tangential misalignment in a direct access storage device adjusts a SID timing window individually for every track or surface of the direct access storage device. The system and method generate a calculation of the tangential misalignment and adjust, in accordance with the calculation of tangential misalignment, a timing window during which the transducer head reads the information located on the storage surface. The calculation of tangential misalignment may be the result of a direct measurement of the tangential misalignment, or may be converted from radial misalignment data. The adjustment of the timing window may comprise opening the timing window an amount depending upon the degree of misalignment of each track, and may comprise shifting the window in time either forward or backward depending upon the nature of the calculated misalignment.

摘要： A system and method for adaptively compensating for real-time variations in mechanical dynamics of a head-positioning assembly during track follow and seek operations. The head-positioning assembly includes a voice coil actuator that positions a read/write head utilizing a coil and carriage in conformity with an actuator control signal. Variations in resonant mode characteristics are anticipated in real-time in accordance with measured temperature variations. These parametric variations are translated in real-time by a state space model to determine a secondary velocity and displacement of the read/write head during track follow and seek operations. In response to this secondary velocity and displacement determination, the actuator control signal is dynamically adjusted to compensate for the determined secondary head velocity and displacement, thereby improving head positioning accuracy and increasing servo bandwidth.

摘要： A data recording disk file having multiple actuators mounted on a common pivot axis, one of the actuators having fewer arms and lower inertia characteristics than the other. A servo system separately drives each of the actuators for seek repositioning, the lower inertia actuator having a higher performance than the other. A controller selectively records one type of data on the data surfaces associated with the lower inertia actuator, and records all other data on the other data surfaces, thereby providing a disk drive with increased performance appropriate to the data stored on the surfaces associated with the lower inertia actuator. A removable locking pin may be provided which extends through corresponding holes in each of the actuators for maintaining the actuators precisely positioned with respect to each other so that servo information may be written on each of the surfaces in a single process. Additionally, one of the actuators may be provided with a shorter stroke than the other actuators. Further, the tracks of the data surfaces associated with one of the actuators may have a different track pitch than the other data surfaces.

The visco-elastic inner core has the properties of very good energy dissipation, while the outer shell provides high dimensional control and stability.
