Abstract
In one embodiment, the invention is directed to techniques for controlling the abrasivity of magnetic tape without modifying the coating formulas used to create the magnetic tape. For example, the invention may involve controlling or adjusting the abrasivity of magnetic tape using one or more burnishing techniques such as lapping, vaming or scraping. In this manner, the abrasivity of magnetic tape can be controlled or adjusted to ensure that the tape meets the necessary tape specifications without modifying the coating formulas applied during the coating process.
