Idea for a new type of hard drive

Postposted on Sat Feb 08, 2003 9:44 am

Now everyone knows that a regular harddrive funcitions by reading/writing data to the disks via the head and arm, But what I am wondering is this: What if you added a second read read to the other side of the dirve? I know it would effectivly make the drive at least 1.5 times as long as it was, but would it result in faster seek and transfer rates? I am also wondering if a drive like this would be possible, considering all the math that goes into one of those things, e.g. getting the heads to search correctly, sync up and such.

Just an Idea.

Sorry for the ignorance, but can you actually read a plate's information on the opposite side of writing?

I don't see any reason why it wouldn't be able too...

Out of curiousity, wasn't this idea posted before here? I remember seeing this same sort of discussion last year.

I think the outcome of that situation was that it would be more difficult to make more logic circuits for the HD in addition to another read head. I think if you do a search for the topic, you might find it.

You're talking about the other side of the platers? I dont quite understand what you mean by other side of the drive. There is already a "arm" for each platter on the drive with heads on each.

Actually someone already did this for a research project. I think it was in Japan, but not sure. It was posted on one of these sites several months ago -- maybe Tech Report or Aces Hardware.

Ya, I remember this posted a year or so ago...it got shot down rather heavily due to some details i dont recall
Your bargaining posture is highly dubious.

it was on slashdot awhile ago, only they had one read/write head and one read only head. It was for helping secure web servers.

Yep, this was discussed before (do a search for "RAIDdrive" if you really want to see it).
Seagate came out with a drive like this some years back:
