Longitudinal Video Recording : ウィキペディア英語版 | Longitudinal Video Recording Longitudinal Video Recording or LVR was a consumer VCR system and videotape standard. ==Comparison with other VCR technologies== LVR differed from other VCR technologies in that instead of running a tape slowly past a pair of rapidly moving recording heads and laying the tracks obliquely across the tape in a helical scan, the LVR ran a tape quickly past a stationary recording head which would step across the tape width and lay down a series of parallel tracks along the tape's length.〔 The head used fixed scanning but moved down the tape to the next track once the end of the quickly moving tape (240 ips with 300 tracks to a ½” tape) had been reached.〔
