摘要： Prevention of deletion of data in an unintended recording layer of an optical disc is ensured even when servo deviation occurs while controlling data reproduction. A light source outputs a light beam with light intensity according to a driving current on which a high frequency signal is superimposed. The light beam is collected on a recording layer of an optical disc. As triggered by detection of servo deviation during data reproduction, a light intensity controller adjusts a superimposed amount of the high frequency signal in the driving current to suit to a specific recording layer with the lowest reproduction tolerance in the optical disc and thereby controls the light intensity of the light beam output from the light source.

摘要： Disclosed is a disk storage apparatus to control writing to a storage medium having a storage area to which a first address space is allocated and whose transfer rate spatially changes, including a command reception section and control section. The command reception section receives a write command from a host apparatus and containing an address of the first address space. The control section performs control to divide the storage area into zones, pre-define a second address space where blocks are successively allocated to the zones from a beginning address of the first address space, replace, for each of the write commands received by the command reception, an address of the first address space contained therein with an address of the second address space, select one of the zones as a write target zone by cyclical changing, and perform a writing process to the storage medium for each selected zone.

摘要： A recording/reproducing apparatus is provided which can write continuously a file of large-capacity at high-speed. A record area of HDD is provided with a disk cache area for temporarily storing data to be written. The disk cache area is defined as a area that is not used by a host apparatus (3) in an LBA space, and the disk cache area is disposed in an area with a high transfer rate such as an outer circumferential area of a disk (10). A file transferred from the host apparatus (3) is written in the disk cache area, and the file is transferred from the disk cache area to a usual user area during an idle period to release the disk cache area and prepare for next transfer data write.

摘要： A timebase corrector is provided, in which an input video signal is written in a timebase error correcting memory on the basis of a clock pulse synchronized with a synchronizing signal in the input video signal and the signal written in the time base error correcting memory is read out on the basis of a read clock pulse synchronized with a reference signal to thereby correct a timebase error. In this timebase corrector, when a drop-out of a first vertical synchronizing signal in the input video signal occurs, the write of the input video signal in the timebase error correcting memory is inhibited, and a timebase error is corrected by the input video signal already written in the memory until a second vertical synchronizing signal is detected.

摘要： A color video signal recording and reproducing method for recording and reproducing a color line sequential TCI signal which prevents, upon different speed reproduction, a possible displacement in hue of a reproduction color video signal. First and second time base compressed chroma signals for one horizontal period are combined with a time base elongated brightness signal for one horizontal period, and type code signals representative of types of the chroma components are added to form encoded color video signals for two tracks. The encoded color video signals are shuffled and recorded simultaneously onto a magnetic tape by two heads. Reproduction color video signals for two tracks obtained by simultaneous reproduction from the magnetic tape are written into and read out from memories each having a plurality of memory areas in accordance with type code signals separated from the reproduction color video signals for two tracks to obtain deshuffled reproduction color video signals for two tracks, which are subsequently decoded to obtain the original color video signal consisting of the brightness signal and first and second chroma signals.
