Magnetic recording medium and head cleaning tape |
摘要 |
This invention provides a magnetic recording medium which, even when the friction time is prolonged or the scan speed is increased to achieve a long time recording, will leave no burnt matters onto a magnetic head, reduce spacing loss, and prevent an increase in error rate. This invention also provides a cleaning tape which, without causing any wear and damage of a magnetic head, will remove the head of burnt matters adherent thereto. They are actually a magnetic recording medium and cleaning tape which hold an antiseize agent containing a compound with a pyridine skeleton and two or more ligand sites. Alternatively, they are a magnetic recording medium and cleaning tape which hold an antiseize agent containing a diketone compound. The antiseize agent may contain a titanium coupling agent, carboxylic acid, and phosphor-containing compound, in addition to the above compound.
