Abstract
A method and system for interleaving storage of data streams on a rotating storage medium of a data storage device comprise dividing the storage medium into a plurality of logical zones. Each logical zone of the plurality of logical zones extends radially from an inner diameter of the storage medium to an outer diameter of the storage medium. Data from a first stream of data is written to a first logical zone of the plurality of logical zones for up to an amount of time corresponding to the rotational speed of the storage medium and the size of the first logical zone.
Claims24
A method comprising:
- dividing a storage medium into a plurality of logical zones, the storage medium having an inner diameter and an outer diameter, each logical zone extending radially from the inner diameter to the outer diameter;
- and
- progressively writing data from a first stream of data to concentric tracks of the storage medium, each track being written from a first boundary of a first logical zone to a second boundary of the first logical zone, within the boundaries of the first logical zone of the plurality of logical zones.
Apparatus comprising:
- a rotating storage medium having an inner diameter and an outer diameter and being divided into a plurality of logical zones, each logical zone extending radially from the inner diameter to the outer diameter;
- a read/write head positioned to access data on the storage medium, the read/write head progressively writing data from a first stream of data to concentric tracks of the storage medium, each track being written from a first boundary of a first logical zone to a second boundary of the first logical zone, within the boundaries of first logical zone of the plurality of logical zones.
A computer readable medium having stored thereon a series of instructions that, when executed by a processor, cause the processor to interleave storage of data streams on a rotating storage medium of a data storage device by:
- dividing the storage medium into a plurality of logical zones, the storage medium having an inner diameter and an outer diameter, each logical zone of the plurality of logical zones extending radially from an inner diameter of the storage medium to an outer diameter of the storage medium;
- and
- progressively writing data from a first stream of data to concentric tracks of the storage medium, each track being written from a first boundary of a first logical zone to a second boundary of the first logical zone, within the boundaries of first logical zone of the plurality of logical zones.
