磁带文献库是现代信息交换的主要介质,是计算机情报检索的重要数据源。它是将二次文献(如文嫡、题录)以计算机可读的格式记录在磁带上,形成二次文献的磁带版。目前世界上出版发行的磁带文献库已超过500种,大部分文摘杂志如化学文摘、工程索引、科学文摘等都发行磁带版,成为信息市场的重要商品。我国引进的磁带已有30种,每年花费外汇达数十万美元。CUJA 磁带的目标就是要研制以我国高校学报为主要信息源的,具有打入世界情报市场能力的磁带文献库。文献磁带一般为1/2寸(12.7mm)宽,1200/2400呎(约366/732米)长,记录
The tape library is the main medium of modern information exchange and an important data source for computer information retrieval. It is the secondary literature (such as Wen, the title) recorded in computer-readable format on the tape, forming a secondary literature tape version. At present, there are more than 500 kinds of tape libraries published in the world. Most digest magazines such as Chemical Abstracts, Engineering Index, Science Digest, etc. have been released as tapes and become important commodities in the information market. There have been 30 kinds of tapes introduced in China, which cost hundreds of thousands of U.S. dollars a year. The goal of CUJA tapes is to develop a tape library that has the ability to enter the world intelligence market with its journals as the main source of information in our country. Document tapes are typically 1/2 inch (12.7 mm) wide and 1200/2400 feet (366/732 meters) long, recording
