Magnetic recording and reproducing apparatus |
摘要 |
A magnetic recording and reproducing apparatus has a supply reel and a take-up reel around which a magnetic tape is to be wound. A first tape guide is provided in the vicinity of a rotary head at the supply reel side and a second tape guide in the vicinity of the rotary head at the take-up reel side. The first and second tape guides are movable in directions of a width of the magnetic tape. A detector detects a height of each of the first and second tape guides. A count value corresponding to the detected height of at least either the first or the second tape guide is obtained by a counter. The height of at least either the first or the second tape guide is adjusted so that the count value becomes equal to a reference value. The count value is set to a specific value when the detected height becomes a reference height corresponding to the reference value after the magnetic tape has been wound around the supply and take-up reels.
