A magnetic tape apparatus for the recording and reproduction of signals, including a magnetic tape having plural data tracks running parallel to an edge of the tape; a multi-track reading device including a multi-track playback head configured to read simultaneously plural of the tracks and output signals corresponding to data recorded on the plural tracks; and a housing in which the tape and the reading device are permanently disposed; wherein the tape is adapted for simultaneous recording of data onto plural data tracks of the tape via external recording heads upon the apparatus being connected to an external recording facility.

Magnetic tape apparatus with housing in which playback electronics and

The invention relates to a method for recording longitudinal track bundles on an information medium. The method involves recording tracking information in special tracks in said track bundles. The special tracks are contiguous between each other. When recording a new track bundle a recording and/or reading head may be positioned using tracking information contained in special tracks of a previously recorded track bundle. Several examples of patterns used for coding tracking information in the special tracks we described.
