I am not entirely new to MD's but its been a while since my last purchase in 2000. I was reading some claims by HHB that their Professional disc is good for archiving up to 50 years. This claim plus the impression I have that good MD recorders with coax inputs can take 48Khz straight off my desk has led me, with help from one of your members to this forum. If I have to revert to real time audio to reload this material at some later stage, this time factor is not a major issue in the overall scheme of things but true sound quality is. I plan to store a mixed version of each of my songs plus each individual track copied seperately. I am wary of computer hard drives and the claims for CD's and DVD's as far as I know come nowhere near the 50 near mark. Are there any opinions out there about such a plan? Is there a decent rackmounted recorder out there that would suit my needs? Coax digital input is a must to work with the rest of my gear. The Tascam MD350 only has optical, and the Pioneer MJ D7 has coax but it is not rack mounted. I am using a MAC G5 with Logic Pro and an AudioPhile M Audio midi interface/audio converter. Thanks in advance
