Article 7851 (10 more) in alt.cd-rom: From: wlsmith@valve.heart.rri.uwo.ca (Wayne Smith) Subject: Mitsumi CD-ROM drives: ->Specification Listing<- Organization: (this space for rent) Date: Wed, 10 Feb 1993 21:56:33 GMT Message-ID: <1993Feb10.215633.2167@julian.uwo.ca> Sender: news@julian.uwo.ca (USENET News System) Nntp-Posting-Host: valve.heart.rri.uwo.ca Lines: 99 Contrary to popular belief :) it seems that Mitsumi can be quick when responding to *potential* customer requests for information. 45 minutes from first phone call, to answering machine, to personal response, to fax-in-hand is not too shabby. Anyways, here are the contents of a 6 page fax that desribes the CRMC-LU005S and CRS-UF series Mitsumi CD-ROM drives... ---------------------------------------------------------------------------- Cover-page Mitsumi CD-ROM DRIVE CRMC-LU005S Printed in Japan, Sept/1992 MPC-Compliant and Photo-CD symbols are shown on this page, along with a picture of the internal-type drive. ---------------------------------------------------------------------------- Specifications: CRMC-LU005S Disc: CD-ROM Mode 1/Mode 2 and CD-Audio disc Disc format: CD-ROM format (ISO 9660 and Yellow-book) Disk Capacity: 12 cm Mode 1: 540B bytes 12 cm Mode 2: 630M bytes Data Transfer rate: Mode 1: 150K bytes/sec Mode 2: 175K bytes/sec Burst: 1.6M bytes/sec Access Time: 12 cm disk, 1/3 stroke: 350 msec Ave. 12 cm disk, full stroke: 650 msec Ave. Error rate, mode 1: 10 exp -12 Interface: Mitsumi interface Power requirements: 12V/.3A (1A peak), 5V/.4A Audio: THD @ 1khz: 0.04% Dynamic range @ 1khz: 92 dB Channel separation @ 1khz: 87 dB S/N ratio @ 1khz: 94 dB Frequency response: +.5/-3 dB (20Hz to 20 khz) Line out voltage: 0.78V rms Headphone out voltage: 0.6V rms Weight: 1.4 Kg Operating condition: 0 C to 50 C, 20% to 85% relative humidity Storage condition: -30 C to 60 C, 10% to 95% relative humidity Operating life: POH: 25000 hours (POH ?) Continuous: 10000 hours Dimensions: Height:42 mm Width:148 mm Length:203 mm Front-loader extends 138 mm Front panel: Headphone jack Headphone volume control Busy LED indicator Features: Half Height Form Factor Mitsumi original "slide-top loading" Direct bus interface (8 or 16 bits) MSCDEX supported Multi Media supported Photo CD supported Audio Playback function Dust proof mechanism 32k ram buffer 350 msec average access time Error correction with erasure function (?) --------------------------------------------------------------------------- The CRMC-LU002S has identical specifications to the LU005S except: Buffer size: 2352 Bytes Access time: 1/3 stroke = 650 msec, full stroke = 1.2 seconds The features of the LU002S are the same as the LU005S except: The interface is 8 bits It does not say that it supports photo cd It does not have a large internal ram buffer The CRS-UF series seems to be an external version of the CRMC-LU002S (it has the same specs). The external drive is 82 mm heigh, 162 mm wide, and 298 mm long, and the front loader extends 133 mm. It has the same features as the LU002S. ------------------------------------------------------------------------------ The fax does not mention the CRMC-FR or the CRS-XP series drives, (they are probably discontinued) but Computer Shopper does. In their Feb/93 edition, CS does a review of thousands of CD-ROM drives, half of which are probably discontinued or are only available in Upper Volta. Anyways, the CRMC-FR is listed as internal full height (!!) Although the model number is not mentioned, it seems that USA FLEX is selling the LU005S for $199. I would guess that the rock-bottom price is around $175. I've heard that the LU005S is on national back-order; is this true? Anyways, enjoy the info... -Later:Wayne-
