The IBM 726 was IBM's first magnetic tape unit. It was a dual magnetic tape reader/recorder developed for use with the IBM 701 and announced on May 21, 1952. This model of tape unit was shipped with the IBM 701 from December 20, 1952 until February 28, 1955. [1] Unlike later IBM 7 track drives, the 726 could read backwards as well as forwards.

IBM's first magnetic-tape data storage devices, introduced in 1952, use what is now generally known as 7-track tape. The magnetic tape is 1 ⁄ 2 inch (13 mm) wide, and there are six data tracks plus one parity track for a total of seven parallel tracks that span the length of the tape.

Abstract: On May 21, 1952, the International Business Machines Corporation announced the IBM Model 726 Tape Unit with the IBM Model 701 Defense Calculator, marking the transition from punched-card storage to digital storage on flexible magnetic tape.

2012年5月21日 · IBM的在线展览表示该驱动器“有一个为726而设计的独一无二的控制系统”，意味着“一个磁带可以在100分之一秒时间内或移动到半英寸之前达到 全速”。 在该驱动器在操作中启动和停止的时候，这是一个重要的功能。 一旦该磁带达到最高速度，即每秒钟75英寸，它可以“每秒读取或写入1.25万个数 字”。 磁带是磁性的，在当时用塑料作底面的背景下显得很独特。 726磁带和它的后续者——命名为727、728和729——代表了当时公众对计算机的想象，因为虽然701 …

从 IBM 发明的世界上第一台磁带驱动器 IBM 726 开始算起，磁带技术发展到今天已经超过了 50 年的历史。 实践证明磁带是所有存储媒体中单位存储信息成本最低、容量最大、标准化程度最高的常用存储介质之一。 尽管越来越多的新技术、新产品开始不断冲击着磁带技术，但是它互换性好、易于保存，加之采用了具有高纠错能力的编码技术和即写即读的通道技术，大大提高了磁带存储的可靠性和读写速度，以其独有的魅力向人们证实着它的不可替代性。 磁带设备主要包括磁带 …

IBM's first magnetic tape unit, the IBM 726, was announced in 1952—the year Thomas J. Watson Jr. became IBM president and the employee population passed 40,000. It was announced with the IBM 701 Defense Calculator, the company's first commercially marketed electronic computer.

The IBM 726 introduced inexpensive coated plastic tape for data storage. Clever vacuum column tape buffers allowed the tape to start and stop quickly.

2012年5月31日 · IBM just celebrated the 60th anniversary of its first computer tape drive, the model 726 Magnetic Tape Reader/Recorder, launched May 21, 1952. But historically there was another unit revealed one year before, the UNISERVO from Remington Rand, Inc.’s Eckert-Mauchly Division to be considered as the first tape drive for a computer, the UNIVAC I.
