[Problem] To easily determine the matching/mismatching between the content and index files recorded on a recording medium when turning on power.[Means for Resolution] On a recording medium 2, there are recorded content files and an index file. The index file is constituted by attribute information of the content files (title text data, thumbnail-image data or the like). In the case of changing (recording or deleting) the content file, the index file is updated after the change. A computer 4 sets up, in a nonvolatile memory 15, status information indicative of being in a predetermined process stage, in the predetermined process stage from a start of changing the content file to a termination of updating the index file. The computer 4, at turning on power, determines the matching/mismatching between the content and index files recorded on the recording medium 2 by utilizing the status information, thus repairing the index file as required.

Disclosed is a content reproduction apparatus that is capable of reducing the processing time required between when the viewer's intention to start reproduction is indicated and when a reproduction image is actually displayed, and obliterates the reproduction start time difference between pieces of content. The content reproduction apparatus includes: selection screen display means (110) for displaying a selection screen; preread instruction generation means (112) for detecting a user's selection operation from the selection screen, estimating the selection of a specific piece of content, and generating a read instruction; content storage means (114) for reading the specific piece of content from a recording medium in compliance with the read instruction and storing the read content; content determination means (116) for determining the content to be reproduced in accordance with an actual selection input; and content reproduction means (118) for reading the determined content from the content storage means and reproducing the read content.

A purifying unit containing an adsorbent is positioned between the discharge outlet of a discharge pipe from which boiled water is discharged, and an extracting chamber, so that boiled water flows into the extracting chamber after detrimental components are removed from the boiled water by the purifying unit. Further, a passage change-over section is provided in order to circulate water through the heater until the water is heated up to a temperature suitable for extraction of coffee, and the passage change-over section allows water to be discharged into the extracting chamber from the discharge outlet of the discharge pipe when the water is heated up to the suitable temperature.

Update processing and the like of an index file relating to change of a hierarchical structure is performed. The index file is recorded in a recording medium with content files. The index file is generated based on attribute information of content files and folders including the content files. Content files and folders form a hierarchical structure in which the folders are in an upper hierarchy. In the index file, a prescribed number of entries (management information areas) corresponding to content files and folders, respectively, are provided. Second index information indicating second entries corresponding to folders or content files positioned in a lower hierarchy of folders in the upper hierarchy is provided at first entries corresponding to folders in the upper hierarchy in a list format. First index information indicating the first entries is provided at the second entries.

The present invention relates to a recording apparatus and a method, a playback apparatus and a method, a recording medium, and a program capable of quickly playing back a picture associated with a unit in which a moving image is encoded. An extraction section 51 extracts one picture from each GOP. A number-of-pixels conversion section 40 reduces the amount of information of the extracted picture by thinning out pixels. A static-image compression section 41 encodes the picture whose amount of information has been reduced by a JPEG technique. A microcomputer 31 associates the encoded picture with the GOP from which the picture has been extracted and controls recording of the picture associated with the GOP onto a disk 45 on which the moving image is to be recorded. The present invention can be applied to a recording apparatus for recording a moving image onto a data recording medium.

A high speed dubbing is to be realized with two recording and/or reproducing units for compressed data. To this end, a magneto-optical disc 32 is read by an optical head 33 and compressed data produced via a decoder 41 are delivered to a memory 14 via a switch 37. The data are then delivered to a magnetic head driving circuit 16 via an encoder 15 for direct writing on a magneto-optical disc 2. In this manner, compressed data are directly dubbed without expansion to realize high speed dubbing.

An optical disc drive is disclosed in which an optical disc on which pregrooves are formed for affording wobble signals frequency modulated by predetermined data signals is driven at a constant linear velocity. Until the time that the data signals obtained upon demodulating the wobble signals are taken out correctly, the reproduced wobble signals are compared with a predetermined reference signal so that a spindle motor for rotating the optical disc is controlled so as to be driven at an approximately constant linear velocity. After it is detected that the data signals obtained upon demodulating the wobble signals are taken out correctly, the spindle motor is driven in a controlled manner on the basis of data signals obtained upon demodulating the reproduced wobble signals so that the spindle motor is controlled so as to be driven at a constant linear velocity. In this manner, the optical disc is controlled immediately at the start time of the optical disc or at the time of track jump by the optical head so that the optical disc is driven a constant linear velocity.

The present invention relates to a recording apparatus and method, a storage medium and a program which allow data for a predetermined playback time to be recorded in a contiguous area on the data storage medium, even when an area in which data cannot be recorded exists on the data storage medium. While a stream unit for a predetermined playback time is being recorded on a storage medium 102, when a recording error occurs, a controller 138 searches for a contiguous blank area greater than the recording capacity of a contiguous recording area in which the stream unit is being recorded. Under the control of the controller 138, a drive 136 secures, in the beginning of the found area, an area having the same capacity as the data amounts of an IL auxiliary area and a recorded stream unit, records an unrecorded stream unit, and then copies the recorded stream unit. The present invention is applicable to video cameras.
