Title: Magnetic tape
Inventor: ONO MASAAKI
IPC: G11B5/73
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To reduce a dropout by providing a ferromagnetic metallic thin film layer on a one side surface A of a polyester film and making the SRa value, SRz value and surface waviness respectively specified ranges. SOLUTION: The SRa value of the ferromagnetic metal thin film layer of this magnetic tape is 2-5nm, the SRz value is 40-70nm, and the surface waviness is 30nm or below. When the SRa value is <2nm, a ferromagnetic thin film of a video tape is weared by a video head at a reproducing time due to too smooth. When the SRa value exceeds 5nm, the output characteristic of the video tape is lowered due to too rough to be undesirable. When the SRz value is <40nm, the durability of the ferromagnetic thin film of the video tape is lowered due to too smooth in repeated recording/reproducing over plural times. When the SRz value exceeds 70nm, the number of Do pieces are increased due to too rough to be undesirable. When the surface waviness is 30nm or above, a contact property between the head and a video tape magnetic layer becomes defect, and the output characteristic is lowered.

Subsequently, a position control is executed so that the position BW and the surface of the member 34 coincide exactly with each other, and a phase difference detected by a phase difference detecting circuit is stored as an initial phase difference. Next, by a horizontal direction driving device 84, the member 34 is brought to stop feed by a minute distance in the horizontal direction, and whether the phase difference detected by the phase difference detecting circuit is varied from the initial phase difference or not is judged. In the case of the negative, the measurement is executed. However, in the case of the affirmative, a position of the objective lens 36 is adjusted so as to return the phase difference to the initial phase difference. Thereafter, a moving distance of the lens 36 is calculated, and from the moving distance of the lens 36 which is stored and a moving distance of the member 34, a shape of the uneven surface of the member 34 is calculated.
