Method to manufacture bit patterned magnetic recording media
View Patent ↗A method to increase the storage density on magnetic recording media by physically separating the individual bits from each other with a non-magnetic medium (so-called bit patterned media). This allows the bits to be closely packed together without creating magnetic “cross-talk” between adjacent bits. In one embodiment, ferromagnetic particles are submerged in a resin solution, contained in a reservoir. The bottom of the reservoir is made of piezoelectric material.
1. A method of manufacture user-defined patterns of nanostructures comprising:
submerging particles in a resin solution contained in a reservoir;
using one or more acoustic wave devices to create standing pressure wave interference patterns between walls of the reservoir to form the particles in patterns;
adjusting the patterns of the particles by tuning the frequency and power of the one or more acoustic wave devices; and
creating staggered layers of particles to increase the density of the particles.
2. The method of claim 1 , wherein the particles are substantially spherical.
3. The method of claim 1 , wherein the particles are ferromagnetic.
4. The method of claim 1 , wherein the particles are diamond nanoparticles.
5. The method of claim 1 , wherein the one or more acoustic wave devices comprise one or more surface area acoustic wave devices.
6. The method of claim 1 , wherein the one or more acoustic wave devices comprise one or more bulk wave acoustic devices.
7. The method of claim 1 , wherein the method is used to manufacture bit patterned magnetic recording media.
