1.引言数字磁带存储器的优点是:容量大、能在可更换的带盘上存储信息以及每位成本极低,因此它是电子数据处理系统中一种重要的装置。磁带机的典型存储容量为10~8到10~9位。用一盘磁带,每位成本为3.6×10~(-5)分;对于装有一盘磁带的磁带存储器,每位成本为1.25×10~(-2)分数字磁带存储器还必须满足新的计算系统在成本和性能方面的要求,也就是说,必须能提供和每种性能要求适合的成本,同时,在所有性能水平上提高信息的可靠性和机器的可维修性。磁带传送机的中心部分是磁带驱动器,它由磁带驱动机构和磁带导向元件组成。磁带驱
1. INTRODUCTION The advantages of digital tape storage are its large capacity, its ability to store information on replaceable tape trays, and its extremely low cost per bit, making it an important device in electronic data processing systems. The tape drive’s typical storage capacity is 10 to 8 to 10 to 9 bits. A tape costs 3.6 x 10-5 points per piece, and 1.25 x 10 -2 points for each tape cartridge containing a tape. The digital tape memory must also meet the new calculation The system’s cost and performance requirements, that is, it must be able to provide the right cost for each performance requirement while improving the reliability of information and the maintainability of the machine at all performance levels. The center of the tape conveyor is the tape drive, which consists of a tape drive mechanism and a tape guide. Tape drive
