Magnetic recorder and/or reproducer of eliminating crosswalk interference in both a long time record mode and a standard record mode

摘要

A magnetic recorder and/or reproducer is provided for preventing a crosstalk phenomenon from occurring between adjacent tracks by a "wide head" during "long time" record mode. The magnetic recorder and/or reproducer includes a rotation drum which has a pair of first heads for recording and/or reproducing during a standard record mode and a pair of second heads for recording and/or reproducing during a long time record mode. The rotation drum also has a pair of flying erase heads whose head width is greater than or equal to the standard record track width of a standard record mode. The pair of flying erase heads is separated from the bottom surfaces of the pair of first heads by a first offset and is separated from the bottom surfaces of the pair of second heads by a second offset. Furthermore, one of the flying erase heads forms a predetermined angle with one of the first heads. Also, the pair of second heads has a head width which is wider than the long time record track width, and the recording time of the long time record mode is longer than that of the standard record mode by a predetermined number of times. With this configuration, the magnetic recorder and/or reproducer is able to remove the crosstalk during the long time record mode.
