Re: [ARSCLIST] Help Purchasing a Microcassette
Bob, thanks for the link. MY HEAD HURTS...
I found this, there:
Drive System: Capstan - MICROCASSETTE, Reel drive - MINICASSETTE
REEL DRIVE??? I had forgotten that Minicassette was REEL/RIM drive
YUCK! Thank goodness we have DC6 and Samplitude 8.
Tape speed: When using the MICROCASSETTE, adjustable -20 to +40% (2.4 cm/sec.)
When using the MINICASSETTE, adjustable -25 to +50%
This unit doesn't handle 1.2 cm/sec (15/32 in/s) which some/many
microcassette recorders can record at and the varispeed is only -20%
so that can't get you there, either. Granted, my approach doesn't get
you anything but 4.8 cm/sec, but with 2x speed reduction, I still
provide 10 kHz bandwidth (more later) and for the 1.2 cm/sec, we
still have 5 kHz bandwidth. On the digital side, we have more, but
I'm limiting the playback bandwidth to 20 kHz for the Dragon - record
with 40 kHz bandwidth.
Frequency Response: 300-4,000 Hz
Here's the "more" This is probably all that the system was rated at,
but machines often record more information than they play back. Hence
my desire to use the Dragon to capture as much as possible (within
limits) of what was recorded.
Oh, and some of the Forensic functions of the JBR CAN be accomplished
on the Tascam 238 8-track cassette player (although it plays at 3.75
in/s (9.6 cm/s).
I understand the need to quickly make an access copy, for which I
think something like this is perfect. But if you're doing
preservation transfers, I think the method I proposed offers a better option.
Cheers,
Richard

from our local university surplus, one was new in the box for only a
