- SPOOL or SPOIL?
-
- MIDICraft informs you of
- how to take care of your DAT tapes
-
- Written by Kevan R.Craft

-
- When you load new DAT (or analogue) tape, fast forward it to the end and
- wind back. This loosens up the tape, and spreads any lubricatants across
- the tape surface. It also allows any loose particles to shake free
- before you start recording. DAT tapes, like analogue cassettes can
- suffer from bump caused by the fixing of the tape into the spool - that's
- why its also safer to leave the first minute or so of any tape blank
- (though you'll need to record silence for DAT's puposes).
-
- As with analogue, using cue and review wears both tapes and heads. Use
- them sparingly. For the same reason don't pause (which leaves the
- tape wrapped around the rotating head) unless you need to drop into record
- quickly.
-
- DAT heads require cleaning regularly. Make sure you use the correct
- type of cleaning cassette. Be prepared to have your DAT recorder
- professionally serviced occasionally. Keep the tapes in a dry and clean
- place. Dry, because the metalic particles can get rusty, and clean because
- a particle of dust looks like a small rock next to a DAT track.
-
- Don't write DAT labels in pencil or ball-point pen. Graphite and ink
- particles can flake off and stick to your head or tapes. Use felt pen or a
- fine marker.
-
- Make backups of your important recordings. The best option is to own,
- borrow, or hire a second DAT recorder, then copy in the digital domain. If
- like me you own a domestic DAT machine like the SONY DTC 690, containing
- the dreaded SERIAL COPY MANAGEMENT SYSTEM (S.M.C.S) which prevents you
- making digital copies beyond one generation, then there are a couple of
- products on the market that will remove this anti-copy protection - for
- example, 'The CopyRite SMCS defeat box' from Audio Design (+44 01734
- 844545), or 'Blade Music's Stripper' (+44 01223 208552).
-
- Editing tapes: once you've prepared masters of several songs, you'll
- want to compile a digital master on a single DAT. You'll need either
- a second DAT recorder, or a hard disk recording system into which you can
- down load your DAT masters, cut and paste, then recorded, all without
- leaving the digital domain. (This feature is NOT available on the AMIGA
- until Commodore get their shit together concerning 16 BIT and the DSP!
- Come on guys, we Amiga musicans are getting left behind with regard to
- this aspect of digital recording on our computers!!! The sooner
- Commodore introduce an Amiga with 16 Bit audio with the DSP the better
- for the future of both the machine and us users alike! As a side note,
- could you Amiga designers PLEASE ensure that the 16 Bit DSP is
- interactive and multi-tasking with a Hard Drive and CD ROM, unlike the
- doomed A570 and CDTV technology!!!)
-
- If there's a chance your work may end up on CD, record at 44.1kHz rather
- than 48kHz. Although the higher sampling rate gives better quality, the
- conversion rate from 48kHz back to 44.1kHz effectively negates any real
- advantage.
-
- While conventional wisdom says avoid overloading your DAT inputs, be aware
- that brief flashes of red from the LEDs aren't necessarily disastrous -
- percussive peaks (such as snare beats) are generally short enogh
- for ugly digital distortion to remain inaudible.
-
- Take your tape out of the machine when you turn it off. This
- saves embarrassing poking around should the machine crash next time you
- turn it on.
-
- When you're working on final mixes, don't re-record over failed attempts -
- just let the tape run, then pick your chosen version. That way, you aviod
- tape wear and lessen the likelihood of errors.
