摘要： In one embodiment, the invention is directed toward inline lapping of magnetic tape. The lapping process is performed inline with one or more other magnetic tape manufacturing processes. In this manner, the number of times the magnetic tape is un-spooled and then re-spooled can be reduced. Consequently, the amount of handling of the individual tape pancakes can also be reduced, thus avoiding damage to the edge of the tape, or other damage associated with tape pancake handling.

摘要： 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.

摘要： A winding flange guide (10) is utilized to provide a better quality wind of a strand media. The guide (10) has a first flange (12) and a second flange (13) which constrain the movement of the outer wraps of the tape pancake formed by the tape media. The winding flange guide (10) is utilized in a servo writer (20), tape cartridge (40, 60) and tape drive (80).

摘要： A method for manufacturing magnetic recording tape includes applying a front coat including a magnetic component to a substrate to provide a coated substrate. The coated substrate defines a first face and an opposing, second face, the first face extending between a first corner and an opposing, second corner, and the second face extending between a third corner and an opposing, fourth corner. An abrasive surface is moved against the first corner of the coated substrate to abrasively remove a volume of material from the first corner. In particular, the abrasive surface is angularly offset at a substantially non-orthogonal angle from the first face of the coated substrate.

摘要： Techniques are described for securing data on data cartridges, such as a Linear Tape-Open (LTO) data cartridge. The techniques include modifying a portion of a cartridge memory (CM) chip of the cartridge in a way that a cartridge drive will be unable to access the data cartridge and to prevent modification of the CM chip by the cartridge drive. In one embodiment, a system includes a data cartridge including a CM chip, a chip reader to read data from and write data to the CM chip, and a computing device to control the chip reader. The computing device causes the chip reader to read data from the cartridge memory chip of the data cartridge and to modify a portion of memory of the chip to prevent unauthorized reads and writes to the data cartridge, without rendering the modification irreversible.
