Who Knows What This Disc Is?

[Dishmop]

I know what it is but anybody else?

 

[REDWOOD]

Very old hard drive disc, some make coffee tables with them

Very old hard drive disc, some make coffee tables with them

never seen them that large but worked with the type behind which i think are IBM7000 series removable disk stacks

 

[Tonych224]

Probably from something like this... Which is a 5MB hard drive.

 

[davnig]

It's amazing really that you can now get 1TB on a thumb drive!!

 

[REDWOOD]

I Believe they were 26 inches in diameter

 

[Luminos]

It's a platter.
And it was disk, not disc

 

[Apple]

Yes a byte sized disc!

 

[Dishmop]

Yes a byte sized disc!

I think it was 20meg.

Likewise, don't recall the massive ones. The drives the big one is leaning against look like CDC 80MB pack drives to me. They were widely sold with many systems, although I don't think IBM used them. Behind them are a row of drives I don't recognise, but are those ICL colours?

I found this information about the platter and an image of a coffee table.

I had forgotten about disc and disk. Thinking about it I suppose its because I probably havent written either word for some considerable time.

Compact disc = c/d.


Hard disk drive = h/dd or hard drive.

optical or magnetic ?

Magnetic. The density of devices on chips has increased over the years, but it has been paralleled by the increasing density of storage on magnetic materials.
