Abstract
A tape head includes a set of one or more segments, wherein each segment of the set is individually movable with respect to a frame; each segment of the set comprising at least one of a write element configured to write data to a tape and a read element configured to read data from the tape; and each segment of the set comprising a further read element having a width transverse to a motion direction of the tape being at least a width of the write element of the segment or, in the event that no write element is comprised in the segment, of a write element of a different segment.
Claims10
A tape head, comprising:
- a set of segments, the set of segments including at least two columns of segments and at least two rows of segments, wherein each segment of the set is individually movable with respect to a frame;
- each segment of the set comprising at least one read element configured to read data from the tape;
- and
- each segment of the set comprising a further read element having a width transverse to a motion direction of the tape being at least a width of a write element of the segment when the segment comprises the write element or, when no write element is comprised in the segment, the further read element having the width at least a width of a write element of a different segment.
A tape storage system, comprising:
- a tape head, including a set of segments, the set of segments including at least two columns of segments and at least two rows of segments, wherein each segment of the set is individually movable with respect to a frame, each segment of the set comprising a read element configured to read data from the tape, and each segment of the set comprising a further read element having a width transverse to a motion direction of the tape being at least a width of a write element of the segment when the segment comprises the write element or, in the event that no write element is comprised in the segment, of a write element of a different segment;
- and
- a controller configured to, for each segment, receive a signal read by the corresponding further read element, determine a frequency spectrum of the signal, and control an actuator for the segment so as to move the segment transverse to the motion direction of the tape subject to the determined frequency spectrum.
