Method and apparatus for recording an information signal on a rotary recording medium

摘要

A method and apparatus for assembling an information signal on a rotary recording medium comprising a pre-recorded track recorded with pre-recorded information signals and an unrecorded track not recorded with information signals by use of a light beam in which an information signal to be newly recorded on the rotary recording medium is recorded continuously from the pre-recorded information signal already recorded on the pre-recorded track. The apparatus by use of a light beam searches for a pre-recorded track turn which is a portion of the pre-recorded track immediately preceding the unrecorded track and continuously reproduces the information signal from the searched pre-recorded track turn as it waits for a command signal commanding the recording of the information signal to be recorded. Responsive to the command signal, the apparatus terminates the repetition of the reproducing operation of the searched track turn and commences the recording on the unrecorded track turn following the searched pre-recorded track turn.
