Title: Information recording medium
Inventor: WADOKORO JUNICHI
IPC: G11B7/2405
Filed: 1990-02-09
Abstract: PURPOSE:To make a light-weight recording medium with improved reliability by forming tracking guide grooves and recording layers on both sides of a glass substrate so that the recording capacity per weight of a glass substrate becomes as about double as that of a medium made of two glass substrates adhered. CONSTITUTION:On both sides of a glass substrate 1b, there are successively formed tracking guide grooves 2, information recording layers 3 including recording films, and hard coating films 5 for surface protection to constitute a double- face disk. By using a glass substrate 1b which has less distortion and low moisture absorption than plastics, reliability of the medium is increased. Moreover, by forming tracking guide grooves 2 and information recording layers 3 on both sides of the substrate 1b, recording capacity is increased while weight increase is suppressed. Thereby, same recording capacity can be obtained for the substrate of about half weight as that of a double-face disk comprising two glass substrates adhered.

Filed: 1983-02-23
Abstract: PURPOSE:To discriminate efficiently whether trimming of melting-away is required or not by picking up the image of a melting-away flame which melts away the outermost layer part of a metallic material and discriminating and detecting components concerning defective sparks from the photoelectric conversion signal of the picked-up image. CONSTITUTION:The melting-away flame is radiated from a melting-away flame nozzle onto a slab running on a carrying roll, and its defective sparks are picked up by a TV camera 6. Its picked-up image is scanned by vertical and horizontal synchronizing signals from a synchronizing signal generator 11, and the picture signal is given to a level discriminating circuit 12 and a differential binarizing circuit 13. The picture signal and its differential signal are compared with respective thresholds; and when they exceed thresholds, a pulse signal is sent to a counter 15 through an AND circuit 14, and clock pulses from an oscillator 16 are counted. The counted value is sent to a grade discriminating circuit 17, and melting-away start and end signals from a melting-away controller 18 are received; and when a maximum value and an average value of counted values during the time between these signals exceed reference values, an alarm is generated to a control circuit of a melting-away trimming device.
