Abstract
An optical data storage apparatus having a focused mass storage medium which remains or rotates in focus about a focal point as data signals are transferred to and from the storage medium. The geometry of the focused mass storage medium permits greater data storage capacity while providing immediate data transfers due to the elimination of travel mechanisms commonly used to align the signal. Further, the apparatus is capable of transferring its entire data storage per rotation of the medium.
Claims6
An apparatus for the storage of data, comprising:
- means for producing a signal;
- optical system means for manipulating and directing said signal;
- storage medium comprising storage domains having radiant energy-active storage means for storing data;
- said storage medium having at least one focal point from whereabouts said signal is directed to and received from said storage medium as said storing data by means of said optical system;
- said storage medium further having curvature in at least two directions such as a primary curvature which geometrically defines the focus of said storage medium providing location/s for said focal point, and a secondary curvature generated about a symmetrical axis of said storage medium,
- whereby, said secondary curvature geometrically alters angles of reflection from adjacent storage domains of said storage medium from an angle of reflection from a selected storage domain of said storage medium with respect to said focal point and said symmetrical axis during a signal transfer operation;
- drive system means for synchronizing the manipulation of said signal from said focal point about said storage medium during a signal transfer operation;
- and
- said optical system includes a signal receiving device means for receiving and processing said signal from said storage medium during said signal transfer operation.
