Abstract
An information recording and reproducing apparatus of the rotary head type which is simple in construction and allows, when record data to be re-record are prepared, only the prepared record data to be re-record in a postrecording mode readily. The information recording and reproducing apparatus comprises a digital mixer which replaces data reproduced from a selected portion of a recording medium with record data to be re-recorded, and the resulted data are supplied by way of a recording circuit to a pair of recording magnetic heads so that they are recorded to the selected portion of the recording medium. The recording magnetic heads are mounted on a rotary head at mounting heights lower than a pair of recording and reproducing magnetic heads disposed on the rotary head. The recording magnetic heads are spaced by 90 degrees in phase from the recording and reproducing magnetic heads and have lower edges adjusted to lower edges of record tracks of a recording medium being reproduced by the recording and reproducing magnetic heads.
