摘要

作者在射电天文学中超长基线干涉测量(VLBI)要求的背景下研究了极宽带，高容量数据存储。他回顾了VLBI磁带录音机的发展历程。他表示，VLBI中对更高灵敏度的需求推动了其中一种工具的开发，即原始数据记录器，现在可以记录128 Mb/s 12小时的数据。他的结论是，基本的磁带和机器技术可以将容量和带宽提高64倍，达到43 TB和1 GB/s，这一点已经得到了证明。然而，一个可行的产品需要进一步的改进和测试关键磁带、磁头和驱动组件、集成通道电子和真正的生产工程。>

The once and future tape recorder

The author examines extremely-wideband, high-capacity data storage in the context of requirements for very-long-baseline interferometry (VLBI) in radio astronomy. He reviews the evolution of VLBI tape recorders. He shows that the need for better sensitivity in VLBI has driven the development of one of those tools, the raw data recorder, which can now record 128 Mb/s for 12 hours. He concludes that basic tape and machine technology to increase capacity and bandwidth with 64-fold to 43 TB and one GB/s has been demonstrated piecemeal. A viable product however needs further refinement and testing of key tape, head, and drive components, integrated channel electronics and genuine production engineering. >
