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
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"
There were two versions of the 5001
- their tape widths:
- differed marginally (approx. 1-2 mm)
- were probably a different brand"
- consequently the tape drums were not
