  • Patent number: 8154811
    Abstract: In a method of electronically measuring reader/writer offset in a tape drive head, a plurality of sequentially adjacent data tracks are written on a tape with a write head. Error rate information is measured while reading a data track of the plurality of sequentially adjacent data tracks with a read head of the tape drive. A bathtub shaped curve is built from a set of the error rate information which is accumulated by reading the data track at a plurality of offsets of the read head relative to the data track. Offset of the read head relative to the write head is measured by determining an offset of the read head which correlates to a magnetic center of the data track as represented by a center point between edges of the bathtub shaped curve.

  • Publication number: 20070097537
    Abstract: To access data on a storage medium, at least three servo stripes simultaneously recorded in a servo track are read. The at least three servo stripes have different orientations on the servo track. An indication of a lateral position of a storage medium access head with respect to the servo track is generated based on reading the at least three servo stripes.

  • Publication number: 20050231906
    Abstract: A mounting apparatus for enabling the mounting of a computer peripheral device to a peripheral device bay of a computer system comprises a mounting rail adapted to slideably engage a profile in the peripheral device bay. The mounting apparatus further includes an adhesive element adapted to attach the mounting rail to a side surface of the computer peripheral device.

  • Publication number: 20050007731
    Abstract: A mounting apparatus includes a mounting rail that is attachable to a side surface of a peripheral device. The peripheral device side surface has a first key profile engageable with a second key profile of the mounting rail so that the mounting rail can be attached to the peripheral device. Alternatively, the mounting rail is attached to the side surface of the peripheral device by use of an adhesive member.
