Erase head alignment
I've got an MCI tape recorder 24 track, I think my erase head is not align properly, theres an erase peak knob on the control card of each track, but I dont really know how to do it, does anybody knows?
How to adjust erase head alignment
There are numerous factors in adjusting for greatest depth of erasure. You must first determine what is not getting erased and how many tracks the erase is not functioning correctly.
If it is an alignment issue, then it could also be part deterioration on some of the bias cards?
Steve at Sonicraft.com (He probably doesn't have an MCI Machine, but I'm sure he's got some idea of what you're dealing with.)
Eddie Ciletti at Tangible-technology.com Ditto for Eddie, but I know he usd to work on them at MCI in Florida many years ago. If anyone knows about these things, he probably does.
No offense, but it sounds like you've got a long way to go and a lot to learn about analog recording in general. If you don't have one yet, you'll probably want to scour the web or elsewhere to find an MCI service manual. (I'm guessing you've got an MCI JH series machine, and they're out there, but you have to look around a bit for them.)
If it is an alignment issue, then it could also be part deterioration on some of the bias cards? Generally, one would print a 1kHz tone at approximately + 10 DB. You would remove tone, rewind, drop the machine into record again while monitoring (with the game cranked substantially high) the playback head (preferably with headphones to avoid bias leakage into your studio monitor tweeters) and start to trim the variable capacitor adjustment for a null of the erased tone. If you can determine that you have reached the null and have properly adjusted the wrap, height and azimuth of the erase head and can still hear the tone lightly in the background, then you have the hot tape problem with the earlier of machine and nothing can be done about it except for changing tape formulations.
