Re: MD: Sony MZ-R90 shock resistance, anecdotal report

2000-05-16 Thread Leon


I don't know if all 831s are built alike, but this happens to mine.

If I place it in my pocket, so that the pickup is moving up-down, it skips
very easily, and takes awfully long to recover. Often there's a noise that
follows this - as if the pickup fell down the worm gear all the way to one
end of its travel.  This has never happened with any other of my portables.
Panasonics do this if I shake them utterly violently, but I haven't "heard"
the same cases anywhere.

The 831 is as good as any other modern portable if I place it in a different
orientation, i.e. so that the pickup travels left-right.

Thought I'd share :)

 Hi,
 
 I have used an MZ-R90 and MZ-R50 in the same pocket of the same shorts
 on the same exercize machine (Nordic track). The MZ-R50 was in use for
 over a year and never once skipped. The MZ-R90 has been in use for the
 last month and has skipped (muted actually) at least 3 times.
 
 Perhaps one could argue that the MZ-R90 is smaller and shifts into a
 more skip prone position in my pocket ... but I think a more likely
 answer is that the MZ-R90 sacrifices some shock resistance for battery
 life.

Indirectly true.  The R90 has a new, smaller, lower power draw mechanism
than the R50, or in fact anything else previously extant.  This new
mechanism appears to be more prone to shock-induced skipping than the
previous mechanism.

Take yer headphones off!! :-)

And then listen to the R90.  You'll hear that about every thirty
seconds, it spins up to read in a blorf of data from the disc and
then shuts down again.  In other words, it's using ~30 seconds of
that 40 second "anti-shock buffer" as a simple data buffer to extend
battery life.  In reality, the R90 has a minimum of about 10 seconds
of shock memory.  No big deal to me, at least.  With blown knees,
I'm never active enough to test it :-(
