Abstract
The present invention divides the recording head into multiple sections, each section accessing a subset of the total number of channels arranged such that one section reads and writes only a subset of the data channels. The sections may be either independently actuated for both coarse (data band) and fine (track-following) positioning, or linked by a common actuator for data band positioning with independent fine position actuators for fine track following.
Claims20
A read/write head assembly for a plurality of data channels comprising:
- a first head section, wherein the first head section accesses a first subset of the plurality of data channels;
- and
- a second head section, wherein the second head section accesses a second subset of the plurality of data channels,
- wherein the first head section and second head section are aligned to access the first subset of data channels and the second subset of data channels concurrently.
A data recording system comprising:
- a read/write head including:
- a first head section, wherein the first head section accesses a first subset of data channels;
- and
- a second head section, wherein the second head section accesses a second subset of data channels;
- and
- an actuator, wherein the actuator positions the read/write head to access the first subset of data channels and the second subset of data channels concurrently.
A method for accessing a plurality of data channels comprising:
- aligning a first head section to access a first subset of the plurality of data channels;
- and
- aligning a second head section to access a second subset of the plurality of data channels,
- wherein the first head section and second head section access the first subset of data channels and the second subset of data channels concurrently.
