Abstract: The present invention relates to an information processing apparatus and method, a program recording medium, and a program which mitigate inconveniences due to a difference in recording format when performing the processing of copying or moving data between two recording media of different recording formats. A device control section 16 supplies UDF data, which is adopted for a DVD, to a device control section 17 together with an ATAPI command used when recording data onto a DVD. The device control section 17 converts the ATAPI command supplied from the device control section 16 into an ATA command corresponding to the ATAPI command, supplies it to an HDD 18 together with data supplied from the device control section 16 together with the ATAPI command, thereby controlling recording of the UDF data onto a hard disk 18A. The present invention is applicable to, for example, a hard disk recorder.

Abstract: A disk recording and/or reproducing apparatus includes a mechanical deck having a disk receiver with a disk carrying unit for carrying a disk, a disk recording and/or reproducing section for recording and/or reproducing the disk received in the disk receiver, and an outer case housing the mechanical deck. A relaxation mechanism and a lock mechanism are disposed between the mechanical deck and the outer case. The relaxation mechanism prevents vibration from being transmitted mutually between the mechanical deck and the outer case. The lock mechanism locks the mechanical deck to the outer case in such a manner as to oppose a relaxing operation of the relaxation mechanism. Thereby, operational vibration, noise and the like caused to the mechanical deck during recordation and/or reproduction can be prevented from being transmitted to the outer case's side.

The movement unit moves the housing section and the recording and/or reproducing unit relative to the arraying direction of plural trays housed in the housing section. The movement mechanism includes a positioning mechanism for positioning the recording and/or reproducing unit relative to a sole tray housed in the housing section.

Abstract: A pair of pins 2c, 2d is arranged on the left and right of each of a plurality of trays 2 placed vertically movably so as to protrude laterally, whereas separating cams 82 are arranged on both sides of the trays 2 in a protrudable and withdrawable way. The separating cams 82 are formed with four first separating control parts 82c1 for moving upward the pins 2c, 2d of the selected tray 2 and the tray(s) 2 thereabove, four second separating control parts 82c2 for moving upward only the pins 2c, 2d of the tray(s) 2 above the selected tray 2, and four third separating control parts 82d each for engaging with only a pair of pins 2c, 2d of the selected tray 2. Movement of the separating cam 82 forms spaces above and below the selected tray 2 to hold a disc on the selected tray 2 from above and below for reproduction on the spot.

Abstract: In an on-vehicle disc player having a disc elevator (22) for making a plurality of trays (2) each having a CD placed on it stacked one over another in the vertical direction move in the stacking direction, there is provided plate springs (2e) for pressing an inserted CD at both sides of the tray (2).
