Dynamax DCR1000 Field Report

Dynamax DCR1000 Field Report


In April, Sony said sayonara to floppy, announcing that it would cease production of 1.44MB, 3.5" floppy disks in March 2011. The 1.44MB format disk was introduced in 1981. In 1998, Apple sold the iMac with no floppy drive at all, which raised many eyebrows at the time. In July 1993, Editor Chriss Scherer wrote a Field Report (at right) for Broadcast Engineering on the Fidelipac Dynamax DCR1000, a digital cart machine that used 3.5" floppy disks as carts. It supported standard high-density 2MB and triple density 13MB diskettes. There were several floppy-based cart machines offered at one time. Do you remember these types of machines?

As homage to a once-great storage technology, we've decided to have some floppy fun.

  • It would take more than 4.32 billion 3.5" floppy disks placed end-to-end to reach the moon.
  • With 1/8" thickness, more than 2.78 million floppy disks would need to be stacked to equal the height of Mount Everest.
  • Robert Pershing Wadlow, the tallest man in medical history had an arm span of 9' 5.75", that's 32.5 floppy disks, end-to-end. The average 5'9" man could hold 19.7.
  • A fully loaded space shuttle including shuttle, tanks, boosters and fuel weighs 4.4 million pounds. That's 117,348,000 floppies.
