摘要:
The data to be recorded onto a recording medium is directly spread and then recorded onto the recording medium through a needle-shaped member, such as a probe. Upon reproducing the data, the data read from the recording medium is de spread and reproduced.
摘要:
A dielectric recording medium unit is provided with: the dielectric recording / reproducing head; a tracking mechanism of the dielectric recording / reproducing head; the dielectric recording medium placed facing to a probe of dielectric recording / reproducing head; and a X-Y stage for parallel-translating the dielectric recording medium. These components are stored in a package. The package is provided with: an electrical connection device for allowing the electrical connection with an external apparatus; and mechanical connection devices for allowing the mechanical connection with the external apparatus. The dielectric recording / reproducing head is provided with: the probe; a return electrode for returning the electric field applied from the probe; an inductor placed between the probe and the return electrode; and an oscillator.

A dielectric recording / reproducing head (40a) is provided with: a probe (11) for recording / reproducing data in / from a dielectric recording medium (1); and a slider (12) placed so as to surround the probe (11) and containing an electric conductor. It may be provided with a probe supporting device (14) containing an insulating member such as resin materials in the gap between the probe (11) and the slider (12). The probe (11) has a longitudinal shape with a longer length in the width direction of the track (5), and covers the track (5) and one portion of adjacent spaces. The slider (12) can be used, by earthing it, as a return electrode for returning a high-frequency electric field applied from the probe (11) to the dielectric recording medium (1) in order to reproduce a signal. The probe (11) is set not to project from a surface of the slider (12) facing to the dielectric recording medium (1).
摘要:
The present invention reduces the waveguide loss in an optical coupling between an optical waveguide layer (10) and a photodetector (2). A multi-layer cladding layer (4,7,8,9) having a first refractive index is formed on a photodetector formed on a substrate (1) by repeating spin-coating and curing of SOG. The cladding layer is formed in such a way as to gently cover a step portion between the photodetector and a light shielding layer (3). An optical waveguide layer (10) which can allow propagating light to be coupled to the active surface (6) of the photodetector is formed on the cladding layer. This structure can suppress steep curvature of the optical waveguide layer above the photodetector.
