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:
There is provided a recording apparatus which includes a recording medium having a data area with an address assigned to each cluster of a predetermined size; an interface for connection to a host apparatus; writing means for writing data in the data area; access order deciding means for dividing the data area of the recording medium into a plurality of areas each having an optional data capacity, and deciding an order of accessing the divided areas from the writing means; timing deciding means for deciding a timing when file information on written data is to be updated; control means for controlling the writing means to access a plurality of divided areas in accordance with the decided access order, search an empty cluster in the accessed area, and write data in the searched empty cluster and file information updating means for updating the file information on already written data.
摘要:
There is provided a composite memory device including a recording medium and nonvolatile recording medium and in which data is written to and read from the recording mediums on the basis of a common file system, the recording medium (10) having a first data area, the nonvolatile recording medium (11) having a second data area and an identification information table to manage the first and second data area collectively. The device further includes an information selector (14) to select positional information including predetermined identification information on the basis of the identification information table, converter (15) to convert positional information selected by the information selector (14) into position information corresponding to the first data area or into positional information corresponding to the second data area, first writing unit to write data supplied from a host device to the first data area and a second writing unit to write data supplied to the host device to the second data area.
摘要:
A data-storage apparatus, a data-storage method and a recording/reproducing system are provided, which effectively use the time elapsing before data is transferred to be written in a recording medium, such as disc-seeking time and disc-rotation standby time, thereby to raise the speed of transferring data. A hybrid storage apparatus has two storage areas, i.e., a disc and a nonvolatile solid-state memory. The disc and the memory have a disc cache area, a system area, and a user area each. If data is transferred from the host apparatus, it is written into the cache area of the nonvolatile solid-state memory that can be accessed at high speed for the first super cluster. While the data being so written, the head is moved to a prescribed position. Any data coming after the head is moved to this position is written into the cache area.
摘要:
An information processing apparatus, a method of controlling the information processing apparatus, a control program for the information processing apparatus and a recording medium having the control program recorded thereon for the information processing apparatus, which may be applicable to a hard disk apparatus for recording video data and the like and providing special reproduction of video data recorded by data-compression, while maintaining compatibility with computers. In a FAT file system, a moving image file management table is formed so as to specify a boundary or limit of each unit of encoding and to utilize the moving image file management table for reproducing moving image files.
摘要:
A bookbinding device is disclosed to adhesively bind a back surface of a stack of pages to a center portion of a cover page, which includes a page supply unit (1), a thickness sensor (2), an adhesive applicator (3), a page conveyor unit (4), a cover supply unit (5), a press unit (8) and a cover folding unit (9). The cover supply unit includes a trimmer (6) for trimming a side edge portion of the cover sheet depending upon thickness of the page stack detected by the thickness sensor, and a positioning unit (7) for positioning the cover sheet such that a center line of the cover sheet which has been trimmed by the trimmer is aligned with a center of thickness of the page stack, at which position the page stack is adhesively bound to the cover sheet.
