ABSTRACT:
The evaluation reference tape includes at least one recess formed on a magnetic recording layer of a magnetic tape by processing the magnetic recording layer. In the method and apparatus for manufacturing the magnetic recording layer, at least one recess is formed on the magnetic recording layer of the magnetic tape by a laser beam or laser beams in a visible region, an ultraviolet region or both which is incident on the magnetic recording layer of the magnetic tape while the magnetic tape is transported in the longitudinal direction. The evaluation reference tape can perform sensitivity correction of a dropout testing apparatus in accordance with a depth or size of a defect of the magnetic tape and evaluation of the recording/replaying system of the magnetic tape without destroying the evaluation reference tape itself. The method and apparatus can efficiently manufacture the evaluation reference tape.
