摘要:
A disk cartridge (1) that holds a disk-shaped recording medium (D) in a cartridge case (2) in such a way that the recording medium (D) can be put into and taken out of the cartridge case (2) comprises a cartridge case body (3) that is composed of top (5) and bottom (6) halves put together with a chamber between them for accommodating the recording medium (D) and having in one side an opening (3a) through which the disk-shaped recording medium (D) is taken out of and put into the cartridge case body (3), a lid (4) that is fitted into the opening (3a) and is slideable in a direction in which the disk-shaped recording medium (D) is taken out of and put into the cartridge case body (3), a stopper removal hole (16) formed in one of the top (5) and bottom (6) halves, a stopper rest (17) formed inside the stopper removal hole (16) and connected to an inner surface thereof, and a stopper (23) whose one end is fixed to the stopper rest (17) and which protrudes into the cartridge case body (3) to stop the lid (4) from sliding.
摘要:
An optical recording medium for accurately deriving the address information or the disc rotation control information despite narrow track pitch and for recording signals to a high density, and a method and apparatus for recording and/or reproducing such optical recording medium. The optical recording medium has a wobbled groove (1) and pits (2) formed at a pre-set interval in an area between turns of the wobbled groove (1). The recording/reproducing method includes controlling (21-23) rotation of the optical recording medium by a wobbled signal from the groove (1) and detecting the position on the optical recording medium of a recording signal by pit signals detected from the pits (2). The recording/reproducing apparatus includes a detection device for detecting the wobbled signal from the groove (1) and a detection device for detecting pit signals from the pits (2). The rotation of the optical recording medium is controlled by the wobbled signals detected from the groove (1) and the position on the optical recording medium of the recording signal is detected by the pit signal detected from the pits (2).
摘要:
A recording medium on which a digital information signal is to be recorded in the form of blocks, each block comprising an information portion consisting of a plurality of subblocks, and a header portion including a plurality of identification data blocks located preceding the information portion and respectively associated with the subblocks, and a system for playing the recording medium to reproduce recorded information therefrom, are disclosed.
摘要:
Method and apparatus for recording and reproducing picture information on a recording medium. In addition to a coded information signal, subcodes together with identification codes for identifying the coding system of the subcodes are recorded in a first recording area of a recording medium and the identification codes and content discrimination codes for indicating contents of information included in the subcode using the coding system indicated by the identification code are recorded in a second recording area of the recording medium. It is further characterized that the identification code and the content discrimination information recorded in the second recording area are displayed at the time of the playback of the recording medium.
摘要:
An apparatus for applying a coating to a surface of a substrate (2) comprises a feeder (4) for feeding the coating to a predetermined position, a roller (3) for applying the coating onto the surface of the substrate (2) and a doctor (10) for regulating the thickness of the coating, the doctor (10) having a rake surface (10d), a facing surface (10c) and a flank surface (10b), forming an escape angle (ϑ₂). The escape angle (ϑ₂), defined between a tangential plane (13) with which the roller (3) is contacted and an extension plane (11) of the flank surface (10b) at an intersection (12) defined between the extension plane (11) and the roller (3), is an obtuse angle.
摘要:
An apparatus for playing a recording medium (20) on which, in addition to a coded information signal, graphic codes including picture information are recorded as being inserted as subcodes into the coded information signal, includes a pickup (22) for reading information recorded on the recording medium and a graphic code detection device (90) generating a graphic code detection signal when the presence of graphic codes in the read signal of the pickup is detected. The apparatus further includes a device (32) for inhibiting a special reproduction operation of the apparatus by which information recorded on the recording medium is reproduced in an order different from a recording order by a track jump operation of an information reading point of the pickup, when the graphic code detection signal is present.
摘要:
Method of recording and reproducing picture information and a recording medium on which the picture information is recorded by the method, and an apparatus for playing such a recording medium. In addition to video format signal and a coded information signal, graphic codes including picture information and instruction codes representing a mixing ratio on each position of a two-dimensional picture formed by the video format signal are recorded on the recording medium after being inserted as a subcode of the coded information signal. At the time of reproduction, signals according to the graphic codes are mixed at each position of the video format signal in accordance with the instruction codes. Preferably, the graphic codes are preferably codes representing the color of each position of the two-dimensional picture, and the instruction codes are codes respectively representing mixing ratios previously determined in accordance with colors represented by the graphics codes.
