摘要： An information signal recording apparatus arranged to form a recording track on a recording medium by recording an information signal on the recording medium, in which the information signal is recorded on the recording medium in such state that a first tracking control signal, for effecting a first tracking operation during reproduction, is superimposed thereon, in the case where a stop of the recording track forming operation is not instructed, and the information signal is recorded on said recording medium in such state that a second tracking control signal, for effecting a second tracking operation during reproduction, is superimposed on the information signal, depending upon a timing when the stop of the recording track forming operation is instructed, whereby a position where the first tracking operation becomes impossible on the way of effecting the first tracking operation during reproduction is detected, so that a position of the step of the recording track forming operation on the recording medium can be easily detected.
