[net.audio] Cassette Recorders

rld@drusd.UUCP (DucharmeRL) (08/27/85)

I have just started monitoring the audio newgroups and was wondering
if anyone has a summary of top end cassette players/recorders (ie like
the nakamichi).  Is it true that some of the tapes that are recorded
on players like the NAK. are not playable on other recorders?

	Thanks in advance

I am answering your question on the net in case others are interested
in similar issues. 

First a disclaimer: I own a NAK BX-100 deck and like it. I must state
that unless you are going to spend 800.00 or more on a cassette deck
(read: too much) that there are several other companies decks you should
consider. AKAI, B&O, HARMON-KARDON, KYOCERA, NAKAMICHI, ONKYO, SONY, and
TANDBERG all make at least one great deck in this price range.

I suggest that the features you might look for to provide good sound and
reliability might include the following:

Direct drive capstans
Closed loop - dual capstans
Sendust alloy head with straight cut gap
LED or fluorescent meters driven from the monitor head (assumes 3 head deck)
3 heads for record monitoring
Solid head block mounting
No auto-reverse unless it is electronic or like NAK'S new type - any head
   rotation type auto-reverse deck is suspect when it comes to reliability
   and recording quality.
Tracking or matched noise reduction encode/decode - see later comments
DBX unless compatibility with Dolby B/C is needed
Dolby HX or HX/PRO unless compatibility with Dolby B/C is needed
Reference mark on meter system of where Dolby cal. level falls
Clean, "mother-board type construction

To answer your question about a NAK recording being incompatible with other
machines - yes this is sometimes true, but it is with other companies decks
too! The problem comes down to tape head gap, tape tracking and complementary
noise reduction encode/decode. The best way I know of to avoid this is:

1) Buy a deck with a Straight Cut head with a typical gap size
2) Get the best noise reduction circuitry you can in your price range
3) Buy a Closed Loop - Dual Capstan tape drive mechanism

Even if you do all of this I can just about assure you that tapes you make
will sound substandard on some decks, this is especially true of car deck
compatibility.

I hope this helps answer your questions.
