To be more specific, you want to get a diskette rated for "Double
Side, Double Density, 96 Tracks per Inch".  The Maxell part number
is MD2-DD.  To summarize:

Diskette description			Mfr/Part No.	Typical Use
--------------------			------------	-----------
Double Side, Double Dens, 48TPI		Maxell MD2-D	IBM PC 360K
Double Side, Double Dens, 96TPI		Maxell MD2-DD	AT&T 3B2
Double Side, High Dens, 96TPI		Maxell MD2-HD	IBM PC/AT 1.2M
