Abstract: A light beam emitted from a laser light source is made incident upon a video disc by means of an objective lens and a light flux reflected by the disc is made incident upon a light detector arranged in a far field of an information track of the disc. The light detector includes four light receiving regions divided in a track direction and a direction perpendicular to the track direction. A first sum of output signals from diagonally aligned two light receiving regions and a second sum of the remaining two light receiving regions are derived and then a sum signal and a difference signal of the first and second sums are formed. The difference signals are sampled by sampling pulses generated at positive going and/or negative going zero cross points of the sum signal to generate sampled values. A tracking error signal is obtained from sampled values.

Abstract: This invention is for a tape cassette having window for insertion of a magnetic head and a pinch roller formed extending from a peripheral wall of the housing of the tape cassette to one of the holding plates which holds a pair of reel hubs in place. The device according to this invention has a shutter member, and a resilient metal wire housed in the housing. The shutter member has projections which are to be engaged with an engaging member provided on a tape cassette holder member of the magnetic tape transport apparatus. The metal wire urges the shutter member to close a portion of the window formed in the holding plate. When the cassette is loaded into the loading member, the projections engage with the engaging member and the shutter member releases the closing state of the holding plate forming portion of the window against an urging force of the wire.
