"卡帶繼續留存"

以為該淘汰你的老舊「混音帶」了嗎？再想想吧！

卡帶或許已經不常用在聽音樂了，但這並不表示它們不能用了。事實上，它們比人們所想的還有用的多。卡帶還是被視為是安全可靠又便宜的儲存方式，可以保存病人病歷和視頻檔案。

就連國際商業機器股份有限公司（IBM）也試圖要保存卡帶，以使其成為綠能儲存科技，來替代相當耗電的硬碟。在蘇黎世，國際商業機器的埃萊夫特里歐和同仁們發展出一種卡帶，體積為10X10X2立方公分，可以保存大約35TB的資料。他們相信他們可以將容量增加到每平方英吋一千億位元。這甚至還可以用在世界最大的資料收集計畫裡。以SKA（平方千米陣）聞名，這個無線電望遠鏡計畫將於十年內開始掃描天空。

因為許多企業並不需要即時取得每樣東西，所以儲存在卡帶裡看起來大有可為，而且還可能因此東山再起。

(Technology) Cassette Tapes Live on

Thought your old mix-tape was obsolete? Think again!

Cassette tapes may not be commonly used for music listening, but that doesnt mean they are not being used. In fact, they are used much more than people may think. Cassettes are still considered a safe, reliable means of cheap, secure storage for things such as patient records and video archives.

Even IBM is trying to keep cassettes alive as a green storage technology alternative to power-hungry hard drives. In Zurich, Evangelos Eleftheriou and his colleagues at IBM have developed a cassette, measuring 10 cm by 10 cm by 2cm that can hold about 35 terabytes of data. They believe they can increase the storage capacity to 100 billion bits per square inch. It may even be used in the worlds biggest data collection project. Known as SKA (Square Kilometre Array), this radio telescope project will start scanning the skies in just over ten years.

Because many businesses dont need real time access to everything, storage on cassette looks promising and may just make a comeback.
