The Magnetic Tape

  • The 5001's magnetic recording tape, another German invention, is about 145 metres long
  • It was manufactured in one-metre widths and then cut to the required width
  • Tapes were usually 10 cm wide
  • Holds 46 hours of recordings
  • When running, the tape winds itself from one vertical cotton-reel-like drum to another at a speed of 11 cms/sec. It was generally considered that the higher the tape speed, the better the recording quality 
  • Schaub-Lorenz sold two different tape colours; a brown and a black one; "black tapes were marginally better in quality than the more common brown ones"[1] 
  • There were two versions of the 5001 model
    - their tape widths:
       - differed marginally (approx. 1-2 mm)
       - were probably a different brand"
       - consequently the tape drums were not interchangeable
