摘要:
A magnetic recording medium having an excellent sliding durability, and including a magnetic layer of a metal magnetic thin film formed on a non-magnetic support body and a carbon protection film formed on the magnetic layer. Recording and/or reproduction is carried out by sliding a magnetic head. The carbon protection film shows, in a Raman spectrum obtained by Raman spectrum analysis using an argon ion laser having a wavelength of 514.5 nm, an intensity ratio A/B of 2 or above for a main peak intensity A appearing in the vicinity of wave number 1550 cm.sup.-1 with respect to a background intensity B.

A circuit board (1) exhibits an average coefficient of thermal expansion (A) of the first insulating layer (21) in the direction along the substrate surface in a temperature range from 25 degrees C. to its glass transition point of equal to or higher than 3 ppm/degrees C. and equal to or lower than 30 ppm/degrees C. Further, an average coefficient of thermal expansion (B) of the second insulating layer (23) in the direction along the substrate surface in a temperature range from 25 degrees C. to its glass transition point is equivalent to an average coefficient of thermal expansion (C) of the third insulating layer (25) in the direction along the substrate surface in a temperature range from 25 degrees C. to its glass transition point. (B) and (C) are larger than (A), and a difference between (A) and (B) and a difference between (A) and (C) are equal to or higher than 5 ppm/degrees C. and equal to or lower than 35 ppm/degrees C.

According to one embodiment, a profile measuring apparatus comprises a profile measuring unit, a position acquiring unit, a profile calculating unit, a deflection detecting unit, and a controlling unit. The profile measuring unit has a projecting unit to project a pattern onto a measured object, and an imaging unit to image the pattern. The position acquiring unit acquires a position of the pattern on the measured object. The profile calculating unit calculates a profile of the measured object, based on image information from the imaging unit and position information from the position acquiring unit. The deflection detecting unit detects deflection of the projecting unit. The controlling unit executes active correction for the profile measuring unit and/or passive correction for the profile calculating unit, based on the deflection of the projecting unit detected by the deflection detecting unit.
