Methods for determining capacity in an alternate mode of optical data storage

Current data storage techniques are based on magnetic and optical technologies such as hard drives and compact discs (CDs) respectively. Research in magnetic technologies has achieved data densities of 100 Gbits/in

(∼15 Gbits/cm

)[1]. With the more recent discovery of optical data storage research has greatly improved data densities with implementations such as the DVD that consists of multiple layers of CDs and Blu-Ray technology that uses a shorter wavelength optical source to decrease the feature size and increase data density up to 2 Gbits/cm

. Although research continues to improve these technologies, both magnetic and optical data storage are limited in their readout speeds due to their serial readout nature.
