Abstract
A method and system for optimizing energy consumption during data read/write operations in a disk-based memory system is provided. The method includes the steps of reading a data clip length, Ls and determining an available energy-optimum recordable track segment.
Claims28
A method for optimizing energy consumption during data read/write operations in a disk-based memory, the method comprising the steps of:
- providing a disk-based memory, the disk-based memory having at least one recordable track, the at least one recordable track having at least one recordable track segment and associated track segment radii R0 . . . Rm,
- reading a data clip, wherein the data clip comprises a data clip length, Ls;
- determining a track segment radius from the associated track segment radii R0 . . . Rm, wherein the track segment radius corresponds to an available energy-optimum recordable track segment from the at least one recordable track, wherein the step of determining the available energy-optimum recordable track segment further comprises the step of making the determination based at least partially on the clip length Ls;
- and
- writing the data clip length Ls on the available energy-optimum recordable track segment.

A system, the system comprising:
- a controller;
- a wireless transceiver;
- and
- a memory, the memory comprising a disk-based memory system adapted to minimize power consumption E during data clip write/read operations based in part on the length of the data clip, wherein the disk-based memory comprises a plurality of disk tracks having radii R0 . . . Rm.
