TU56 DECTape magnetic tape drive

DECtape used double recording to reduce the error rate. It was said that tape perforated with a hole punch would still work.

TU56 DECTape磁带机

DECtape使用双重录音来降低错误率。据说用穿孔打孔的胶带仍然可以使用。


Magnetic Tape

Magnetic tape began as a medium for audio recordings in the 1930s. In 1951—six years before the first magnetic disks—UNIVAC introduced tape drives for computers.

Tape was a storage mainstay for many years and still survives, thanks to its low cost, portability, unlimited offline capacity, and standardized formats that make tapes interchangeable.

有道翻译

磁带

磁带在20世纪30年代开始作为录音的媒介。1951年 - 第一批磁盘前六年 - UNIVAC推出了用于计算机的磁带机。

磁带作为存储支柱已存在多年,并且由于其低成本,便携性,无限的离线容量以及使磁带可互换的标准化格式而仍然存在。



Magnetophon tape recorder

The German Magnetophon was used mostly by radio stations, but also for military communications. Its factory was heavily bombed during World War II.

StorageTek 4400 ACS磁带库

该磁带机器人在斯坦福直线加速器中心(现为SLAC国家加速器实验室)的实验中存储数据,提供对大量数据的中速访问。



UNIVAC I System

UNIVAC I used mercury delay lines for main memory and magnetic tape for storage. The tape drives, called “Uniservos,” are shown at the back.

有道翻译

UNIVAC I系统

UNIVAC我使用水银延迟线作为主存储器和磁带进行存储。称为“Uniservos”的磁带驱动器显示在后面。



UNIVAC metal tape reel

Surprisingly heavy, these 1200 foot reels of ½ inch metal tape were used on the UNIVAC I computer’s “Uniservo” tape drive, the first tape storage device for computers. Each metal tape held about 3MB.

有道翻译

UNIVAC金属磁带卷轴

令人惊讶的是,这些1200英尺长的½英寸金属胶带被用在UNIVAC I计算机的“Uniservo”磁带机上,这是第一台用于计算机的磁带存储设备。每个金属带保持约3MB。




Tape reel (160 MB)

IBM established a standard for 10 1/2 inch tape reels that lasted over 25 years. Over time the recording density and hence the capacity of the tape increased by many times.

有道翻译

卷带(160 MB)

IBM建立了一个持续超过25年的10 1/2英寸磁带卷的标准。随着时间的推移,记录密度和磁带的容量增加了许多倍。



IBM 726 magnetic tape drive

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

有道翻译

IBM 726磁带机

IBM 726推出了廉价的涂层塑料带,用于数据存储。巧妙的真空柱磁带缓冲器允许磁带快速启动和停止。



DECtape drive on PDP-11

Introduced in 1963, reliable and inexpensive DECtape was used in many generations of DEC minicomputers.

有道翻译

在PDP-11上驱动驱动器

在1963年推出,可靠和廉价的DECtape被用于DEC小型计算机的许多代。



DEC VAX with Digital Linear Tape (DLT) drive

Designed originally by DEC, DLT technology was purchased by Quantum in 1994. The drive wrote 22 data tracks back and forth on ½” wide tape.

有道翻译

DEC VAX采用数字线性磁带(DLT)驱动器

最初由DEC设计,DLT技术于1994年由Quantum购买。该驱动器在½“宽带上来回写入22条数据轨道。





DEC CompacTape cartridge

Later standardized as Digital Linear Tape, this replaced the aging 1960s-era DECtape. DLT evolved dramatically, from 92 MB in 1984 to 800 GB with the 2006 "SuperDLT" format.

有道翻译

DEC CompacTape墨盒

后来标准化为数字线性磁带,这取代了20世纪60年代老化的DECtape。DLT发展迅速,从1984年的92 MB到2006年的“SuperDLT”格式的800 GB。



IBM 3850 mass storage system

The largest 3850 storage system held 4,720 cartridges, stored 236 GB, and was 20 feet long.

有道翻译

IBM 3850海量存储系统

最大的3850存储系统拥有4,720个盒式磁带,存储236 GB,长20英尺。




IBM 3850 Mass Storage System: honeycomb section with tapes (50 MB)

As an alternative to a manual tape reel library, IBM introduced this system with 4 inch long cylinders of magnetic tape that were retrieved and replaced by a robotic arm.

有道翻译

IBM 3850海量存储系统:带磁带的蜂窝部分(50 MB)

作为手动磁带卷轴库的替代品,IBM推出了这种带有4英寸长磁带的磁带系统,这些磁带由机械臂取回并替换。



IBM 3480 magnetic tape subsystem

This drive read and wrote 18 tracks of data simultaneously on ½” tape. Each cartridge held 200 MB.

IBM 3480磁带子系统

该驱动器在½“磁带上同时读取和写入18个数据轨道。每个墨盒保持200 MB。




IBM 3480 tape cartridge (200 MB)

This magnetic tape cartridge was fast, reliable, durable and inexpensive. Introduced in 1984 and first used on mainframe computers, it replaced the standard 10.5" circular reel of magnetic tape that had been a feature of large computer systems since the 1950s.

有道翻译

IBM 3480磁带盒(200 MB)

这种磁带盒快速,可靠,耐用且价格低廉。它于1984年推出并首次用于大型计算机,它取代了自20世纪50年代以来一直是大型计算机系统特征的标准10.5“圆形磁带卷轴。
