摘要： The polytetrafluoroethylene (PTFE) porous film of the invention is characterized in that the film is formed from a PTFE resin molding powder obtained by suspension polymerization and has a porosity of 40 to 80%, and removal ratio of uniform particle having a 0.2 .mu.m diameter of less than 99% or bubble point of not less than 3 kg/cm.sup.2. This PTFE porous film is obtained by a process of compression-molding a PTFE resin molding powder to prepare a preform, sintering the preform at a temperature not lower than its melting point, processing the preform into films, then laminating at least two of the obtained films, fusing the films to unite them, and subjecting the obtained film to uniaxial or biaxial stretching at a temperature not higher than the melting point of PTFE. If desired, the finally obtained film may be subjected to heat setting. In the PTFE porous film of the invention, pores are nearly round and the diameters of the pores are almost uniform. Further, the porous film of the invention has a high porosity and is excellent in mechanical strength, so that the film is free from the occurrence of pinholes even when the thickness of the film is made small. According to the processes of the invention for preparing a PTFE porous film, a PTFE porous film having the above-mentioned excellent characteristics can be efficiently prepared by a sequential biaxial stretching or the like, and the obtained PTFE film does not suffer any breakage.

This PTFE porous film is obtained by a process of compression-molding a PTFE resin molding powder to prepare a preform, sintering the preform at a temperature not lower than the melting point of the unsintered PTFE, processing the preform into films, then laminating at least two of the obtained films, fusing the films to unite them, and subjecting the obtained film to uniaxial or biaxial stretching at a temperature not higher than a melting point of the sintered PTFE. If desired, the finally obtained film may be subjected to heat setting. In the PTFE porous film of the invention, pores are nearly round and the diameters of the pores are almost uniform.

摘要： A method for inspecting an optical information storage medium includes the steps of: irradiating the storage medium with a laser beam and rotating the medium by a constant linear velocity control technique by reference to the radial location at which the laser beam forms a spot on the medium; changing the rotational velocities according to the radial location on the medium between at least two linear velocities that include a first linear velocity Lv1 and a second linear velocity Lv2 higher than the first linear velocity Lv1; generating a focus error signal and/or a tracking error signal based on the light reflected from the medium; performing a focus control and/or a tracking control on the laser beam that irradiates the medium based on the focus and/or tracking error signal(s); and passing the branched outputs of control loops for the focus and/or tracking error signal(s) through predetermined types of frequency band-elimination filters for the focus and/or tracking error signal(s) to obtain residual errors of the focus and/or tracking error signal(s) and comparing the residual errors to predetermined reference values.
