Latest Patents

Among his notable latest patents are:

1. **Magnetic Recording Medium Comprising Acicular Dendrite Free Iron Oxide**: This invention describes a magnetic recording medium that includes a non-magnetizable substrate and a magnetizable layer coated onto it. The magnetizable layer contains a high percentage of acicular, substantially dendrite-free iron oxide magnetic pigment particles dispersed within a polymeric binder. This innovation aims to improve the efficiency and durability of magnetic recording mediums.

2. **Method for Making Stretched Surface Recording Disk**: This patent outlines a method for creating stretched surface recording disks (SSR) that feature raised annular ridges at both the inside and outside diameters. It details how an annular recording medium film is held in radial tension across the base portion, secured with an electron beam cured adhesive. This process reduces the time needed to adhere the recording medium to its support while enhancing the bond's quality. As a result, SSR offers higher bit density compared to conventional floppy disks and improves resistance to 'head crashes' experienced with rigid disks.
