    • An apparatus of the present invention is a magnetic recording/reproduction apparatus for pulling out a magnetic tape from a cassette, forming a predetermined tape drive system with a group of tape guide posts while winding the magnetic tape around a rotary head cylinder, having a rotary head, for a predetermined arc, so as to perform recording/reproduction of the magnetic tape. The apparatus includes: an inclined post around which a non-magnetic side of the magnetic tape from the rotary head cylinder is wound; a rail provided integrally with a base on which the rotary head cylinder is mounted; and a tape guide post carrier which has the inclined post mounted thereon and is guided along the rail. The inclined post is a tape guide post around which the winding contact line, along which the magnetic tape contacts the tape guide post, is not perpendicular to a tape drive direction. The inclined post has a tapered tip portion whose diameter upwardly decreases, wherein an upper edge of the magnetic tape is between a base of the tapered tip portion and a tip of the tapered tip portion.
    • 本发明的装置是一种用于从盒子中拉出磁带的磁记录/再现装置,在将磁带卷绕在旋转磁头气缸周围的同时形成具有一组磁带引导柱的预定磁带驱动系统, 头,用于预定的弧,以便执行磁带的记录/再现。 该装置包括:卷绕有来自旋转磁头气缸的磁带的非磁性侧的倾斜柱; 与安装有旋转磁头气缸的基座一体地设置的轨道; 以及具有安装在其上并沿轨道引导的倾斜柱的带引导柱载体。 倾斜柱是磁带引导柱,磁带与磁带引导柱接触的绕组接触线不与磁带驱动方向垂直。 倾斜柱具有直径向下减小的锥形尖端部分,其中磁带的上边缘在锥形尖端部分的基部和锥形尖端部分的尖端之间。
