Latest Patents

Kulkarni's latest patents include a magnetic tape recording system that features a tape with defined remanent magnetization. This innovation allows for reduced magnetic flux modulation and an improved signal-to-noise ratio. By providing a magnetic recording layer with a more uniform thickness, the magnetic flux modulation characteristic can be enhanced. For instance, the magnetic recording tape may have a coercivity of greater than or equal to 2000 Oe, with a magnetic flux modulation characteristic exhibiting a one sigma standard deviation of less than 0.06. In some instances, this characteristic may even reach a one sigma standard deviation of less than 0.05 or 0.04. Such advancements in magnetic flux modulation can support increased storage densities.

Another significant patent involves a magnetic recording medium that also demonstrates reduced magnetic flux modulation and an improved signal-to-noise ratio. This medium can take the form of either a magnetic tape or a magnetic disk. Similar to his previous work, providing a magnetic recording layer with a more uniform thickness enhances the magnetic flux modulation characteristic. The magnetic recording medium may also have a coercivity of greater than or equal to 2000 Oerstads, with a magnetic flux modulation characteristic having a one sigma standard deviation of less than 0.06.
