Abstract: The present disclosure relates to an information processing device and a method, in which an image quality improvement technology required for reproducing contents can be easily used. Image quality improvement technology information regarding an image quality improvement technology for improving an image quality of an image to be encoded is generated, a content file storing the encoded data of the image is generated, and the image quality improvement technology information is stored in the content file. Furthermore, encoded data of an image to be reproduced is acquired from a content file on the basis of the image quality improvement technology information regarding an image quality improvement technology for improving an image quality of an image, and the encoded data is decoded. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.

Abstract: A magnetic recording medium which has dynamic range (I) of 70 dB or more and dynamic range (II) of 45 dB or more in control of a thickness of a magnetic layer and magnetic characteristics wherein said dynamic range (I) is given as a difference between an output at 3% input level of third harmonic wave output at a wavelength of 237.5 .mu.m in the optimum bias recording by a head having a recorded width of 1 to 1.1 mm based on an output of the original signal and a reproduced output calibrated by auditory sense calibration at non-signal recording in the bias and said dynamic range (II) is given as a difference between a saturated output at a wavelength of 4.75 .mu.m under the same condition and the reproduced output calibrated by the A-curve calibration at non-signal recording in the bias.

Abstract: A magnetic recording medium comprises a substrate coated with a magnetic composition comprising a cobalt adsorbed iron oxide powder with a phosphoric ester type anionic surfactant at a ratio of 2 wt. % or more and a binder at a ratio of said iron oxide powder to said binder of 4 or more.A magnetic recording medium has a coercive force Hc of 950 to 1200 Oe and a residual magnetic flux .phi..sub.r of 0.35 to 0.6 maxwell.

Abstract: A magnetic recording medium comprised of a nonmagnetic base and a magnetic coating layer thereon, said magnetic coating layer comprises ferromagnetic particles dispersed in a binder vehicle, characterized in that said magnetic coating layer contains a glyceride and a sorbitan ester of fatty acid.

Abstract: A magnetic coating material for magnetic recording media is produced by dispersing a magnetic coating material containing from 0.1 to 2.0% of an abrasive and from 0.05 to 1.0% of a betaine type ampholytic antistatic agent, both on the basis of the amount of a magnetic powder, in a dispersion mill using steel balls. The abrasive has a hardness of not lower than 6 on Mohs' scale.
