Summary
[edit]DescriptionBasf-80mb-storage hg.jpg | A "Removable Disk Pack" with about 40 cm diameter (see meter at lower edge), which was a storage medium for computer data in the 1970s for professional use only. The corresponding disc drive necessary had about the size of a household washing machine or dish washer. The shown item from BASF had a capacity of 80 MByte, which was an enormous amount of data for the time - as data was primarily text and numbers, because computer-based hi-res graphics, digital audio and digital video had not been invented then or where only concepts and experiments in laboratories and the brains of computer scientists. |
