Abstract
An apparatus according to one embodiment includes a first block, a second block, and a drive mechanism configured to cause a magnetic recording tape to move over the blocks. Each of the blocks has a skiving edge along a tape bearing surface thereof. The blocks are positioned or selectively positionable in the apparatus to establish a particular respective wrap angle of the magnetic recording tape approaching the respective skiving edge. None of the blocks have a transducer coupled directly thereto.
Claims20
An apparatus, comprising:
- a first block;
- a second block,
- wherein each of the blocks has a skiving edge along a tape bearing surface thereof;
- and
- a drive mechanism configured to cause a magnetic recording tape to move over the blocks,
- wherein the blocks are positioned or selectively positionable in the apparatus to establish a particular respective wrap angle of the magnetic recording tape approaching the respective skiving edge, and
- wherein none of the blocks have a transducer coupled directly thereto.
A computer-implemented method, comprising:
- causing a magnetic recording tape to pass over a skiving edge of a block at a wrap angle of at least one degree for burnishing the magnetic recording tape, wherein the block has an average hardness of at least about 9 Mohs, wherein the block has no transducer coupled directly thereto;
- and
- laterally adjusting the position of the block to introduce lateral movement of the block relative to the magnetic recording tape during movement of the magnetic recording tape over the block for helping prevent formation of scarring on the block.
A computer-implemented method, comprising:
- causing a magnetic recording tape to pass over a skiving edge of a block at a wrap angle of at least one degree for burnishing the magnetic recording tape,
- wherein the block has an average hardness of at least about 9 Mohs,
- wherein the block has no transducer coupled directly thereto;
- and
- introducing jitter to the magnetic recording tape during movement of the magnetic recording tape over the block.
