    • A method of storing data includes receiving general purpose (GP) data and special Error Tolerant or Streaming (ETS) data, storing the GP data using a data storage method, and storing the ETS data using a different data storage method which affects the access rate, resilience to errors, data integrity, storage density, or storage capacity. The storage medium, which can include a disk drive, flash memory, or holographic memory, is utilized differently depending on the required Quality of Service in aspects including block size, storage of error correction codes, utilization of error correction codes, storage area density, physical format pattern, storage verification, or reaction to failed storage verification. For disk drives these differences include spacing between tracks; overlap between tracks; spiral track formatting; concentric track formatting, and size of blocks, and for flash memories these differences include levels per cell and number of cells.

    • A method for adapting a control system governing the swing of an actuator arm to the actual deceleration capacity of an attached servomechanism, comprising: maximally accelerating the actuator arm; measuring the actual acceleration; calculating the ratio between the actual acceleration and nominal acceleration; multiplying an actual distance parameter by the ratio before indexing into a velocity profile to retrieve a target velocity; and multiplying a feedforward signal by the ratio prior to feeding it into a control loop. The apparatus includes a servomechanism that swings the actuator arm; a transducer that produces a signal representing the arm's position; a ROM containing a velocity profile; a microprocessor connected to the transducer and ROM, controlling the velocity of the actuator arm such that it tracks retrieved target velocities by outputting a control signal, and a power amplifier connected to the microprocessor and servomechanism, for receiving the control signal and driving the servomechanism.
