Patent number: 7079351Abstract: An improved magnetic tape guiding device for use with a magnetic tape transport system of a tape recorder and the like, and a method for using the same. The magnetic tape guiding system of the tape recorder transport system has a supply reel pole base assembly having a slant pole with a first guide unit having portions formed at both ends of the slant pole to function as a conventional roller for regulating upward and downward movement of the upper and lower edges of a moving magnetic tape, and a tension pole assembly having a tension pole with a second guide unit having portions formed at both ends of the tension pole to function as a conventional impedance roller for regulating upward and downward movement of the upper and lower edges of the moving magnetic tape. This arrangement can thus achieve 2-dimensional plane-traveling of the magnetic tape while also reducing the number of the parts of the guiding system.Type: GrantFiled: January 8, 2003Date of Patent: July 18, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Seung-woo Lee, Bong-joo Kim, Do-young Choi, Jae-hoon Sim, Byeng-bae Park, Young-ho Cho, Jeong-hyeob Oh, Hyeong-seok Choi
