Abstract
Each of slave recorders includes a rotary drum, heads mounted on the rotary drum at positions spaced from a phase reference position on the rotary drum by different angular intervals respectively, and an arrangement for selecting at least one from the heads as an active head in accordance with a designated recording mode. Non-delayed stream data are delayed by a delay time interval to form delayed stream data. A distributor operates for distributing the delayed stream data to the slave recorders. Each of the slave recorders records the delayed stream data on a slave recording medium by the active head. The delay time interval corresponds to the angular interval between the phase reference position and the position of the active head.
