Abstract
A method for converting an opaque portion of a side-group liquid crystalline polymer body into a transparent portion. The method involves applying sufficient shear force to the polymer body for a sufficient time to convert the opaque portion into a transparent portion. The method provides for erasure of opaque optical pixels from data storage disks without requiring the use of electrical or magnetic fields.
Claims23
A method for converting an opaque portion of a side-group liquid crystalline polymer body into a transparent portion, said method comprising the step of applying sufficient shear force to said opaque portion of said side-group liquid crystalline polymer body for a sufficient time to convert said opaque portion into a transparent portion.
A method for storage of optical data wherein data is stored as one or more opaque pixels on a transparent data storage plate comprising a side-group liquid crystalline polymer, wherein the improvement comprises the step of erasing said opaque pixel by applying sufficient shear force to said opaque pixel for a sufficient time to convert said opaque pixel into a transparent one.
A transparent side-group liquid crystalline polymer body which is made by the method comprising the step of applying sufficient shear force to said polymer body for a sufficient time to convert any opaque portions present in said polymer body into transparent portions.
