ABSTRACT:
On a record medium, a moving control information to control a moving speed of a record medium when recording the record information onto the record medium is recorded by wobbling an information track at a frequency corresponding to the moving control information, and a record control information to control recording or reproducing the record information onto or from the record medium is also recorded in advance by forming a pre-pit on an adjacent track, which is adjacent to the information track. An information recording apparatus for recording the record information onto the record medium is provided with: a pickup device for simultaneously emitting a light beam onto the information track and the adjacent track and then outputting a reproduction signal based on a reflection light from the information track and the adjacent track of the emitted light beam; an information extracting device for extracting the moving control information from the outputted reproduction signal; a moving control device for controlling the moving speed of the record medium on the basis of the extracted moving control information; and a recording device for recording the record information onto the record medium while the record medium is moved at the controlled moving speed.
