A near-field optical probe has a hole penetrating through a substrate and defining a microscopic aperture at an apex thereof for generating or scattering near field light. The probe is simple and inexpensive to produce and may be manufactured in an array form by forming plural holes in the substrate so that it may be used in an optical memory device. A lens is disposed above the microscopic aperture for focusing incident light and a light source is arranged thereover to introduce light to the lens. A focal point of the lens is positioned at the microscopic aperture, so that the light emitted by the light source can be efficiently collected at the microscopic aperture. The structure can be mass produced using known silicon processing techniques, thus being adapted for use as an optical memory head.

In the information recording an reproducing method and apparatus according to the present invention, a piece of picture image information is recorded as an analog quantity or a digital quantity an information carrying medium in a planar manner at a high density, charge potential is read for outputting electric signals to correspond to the recorded picture image information and then the outputted signals are printed out by means of various display unit or output device, with high quality and high resolution as well as ease processing of the information. The information carrying medium provides a long period of storage of information and enables stored picture image information to be repeatedly reproduced with a picture quality according to need. Particularly, it is, according to the present invention, possible to read and output local potential of an information carrying medium with predetermined scanning density at a desired time, and so pictures of high quality may be output as a silver salt photograph is taken and reproduced by optically scanning the film. Thus, the present invention may be applied to a wide field including photographing, copying and printing.

The holographic digital data storage system is compatible with a CD/DVD player. A polarization direction of the beam is altered by a first wave plate and the size of the polarized beam is expanded by a beam expander. The expanded beam is split into a vertical polarized beam and a horizontal polarized beam by a polarization splitter; a polarization direction of the horizontal polarized beam is altered by a second wave plate. An optical path of the vertical polarized beam is adjusted by a first mirror to generate a first path-controlled beam; an optical path of a third directional polarized beam is controlled by a second mirror to generate a second path-controlled beam; the first and the second path-controlled beams are concentrated by using a first and a second lenses, respectively; and the interference of two beams is recorded on a medium.

A method and a system for generating optical waveforms from electrical signals is disclosed. An input electrical signal is sampled to obtain a single channel data which is converted to multi-channel data. The multi-channel data is converted to multi-channel electrical pulses which are input along with a light source output into a switch array containing optical switches to obtain a multi-channel optical waveform made up of a plurality of optical waveforms. These waveforms are superpositioned to generate a stacked optical pulse. Alternatively, the multi-channel data may be converted to a multi-channel optical pulses. The stacked optical pulse may be used to write data to a storage medium.

A multi-byte, random access, mass storage/memory system is capable of storing multigigabytes of information and communicating that information over various standard output channels at high transfer rates. The system includes drive, software and media components configured to operate with no moving parts or substantially no moving parts. The system stores/retrieves data from a non-rotational media using an optical head that concurrently sweeps multiple parallel data tracks. The non-rotational media is a high density, rewritable/erasable structure capable of storing large amounts of digital information. The media has an open form factor based upon single cell zones which can accommodate various storage requirements. Also, the mass storage system has an internal bus structure that allows the system to act in isolation or multiple systems to act independently, but in concert for mass storage for one or more hosts.
