摘要:
A method and apparatus for correcting an angular deviation which is applicable to an optical recording medium comprising a data recording region or regions defined by a reference line or lines having and data tracks perpendicular to the reference line or lines provided in the or each of the data recording regions for correcting an angular deviation on a data recording layer of said optical recording medium when the data is read by said photodetective sensor.The angular deviation is corrected by reading, by a photodetective sensor, a position of a reference line of the optical recording medium within a sight of the photodetective sensor at least at two points in the length of the reference line to detect a deviation of the reference line within the sight of said photodetective sensor from a difference between the positions of the reference line read at said points; detecting an angular deviation from said deviation and a distance between said points where the position of the reference line are detected; and correcting said angular deviation on the basis of the detected angular deviation value.

This invention relates to a camera of a type for writing or reading out information on or from a magnetic track provided to a film using a magnetic head. This invention provides a camera of the type which has a regulating member which contacts an end face, in the widthwise direction, of a film to regulate the position, in the widthwise direction, of the film, and in which a surface portion, near the regulating member, of a surface formed between inner and outer rails of a camera main body is formed at a higher level than that of the remaining surface, thereby minimizing deformation of the film on the surface between the inner and outer rails when the end face of the film is regulated by the regulating member.
摘要:
A length-extentional quartz resonator has a pair of linearly arranged longitudinal oscillating portions supported to undergo dominant length-extentional oscillation having an oscillating frequency in the range from 1.04 MHz to 1.06 MHz. A rectangular frame member is arranged to support and surround the oscillating portions and has the outer overall length of 4000 .mu.m.+-.200 .mu.m. The frame member has a pair of longitudinal frame portions connected to the oscillating portions through transverse support portions to undergo flexual oscillation, and having width set in the range from 110 .mu.m to 260 .mu.m effective to suppress coupling between the dominant length-extentional oscillation and the flexual oscillation.
