Abstract
An information reproduction apparatus includes plural magazines in which optical discs are set, plural drives for performing recording and reproduction on an optical disc set therein, a changer mechanism that transports a magazine between its setting position and one or more drives and mounts and remove a prescribed optical disc or discs in and from the one or more drives by performing either one of a single move process and a multi-move process, and a controller. The controller judges whether to conduct the single move process or the multi-move process based on a reading data list and use statuses of the respective drives.
Claims8
An information reproduction method for reading out data from a disc apparatus containing plural optical discs as information recording media,
- wherein the disc apparatus is configured to set plural magazines therein at respective setting positions of the disc apparatus;
- wherein the optical discs are set in the magazines in each of which plural optical discs can be set;
- wherein the disc apparatus comprises:
- plural drives each of which is configured to perform recording and reproduction on an optical disc set therein;
- and
- a changer mechanism configured to transport a magazine between its setting position and one or more drives and mounts and remove a prescribed optical disc or discs in and from the one or more drives by performing either one of a single move process and a multi-move process;
- wherein in the single move process, a prescribed optical disc that is set in the magazine is transported and mounted in and released from the drive while the magazine is reciprocated once between its setting position and the drive;
- wherein in the multi-move process, prescribed N optical discs that are set in the magazine are transported and mounted in and released from N respective drives while the magazine is reciprocated once between its setting position and the drives, N being an integer that is larger than or equal to 2,
- the information reproduction method, comprising:
- judging whether to conduct the single move process or the multi-move process as a transport process for transporting optical discs to respective drives to read data from them based on use statuses of the respective drives and a reading data list, the reading data list containing disc information that enables identification of optical discs storing reading data to be read out, area information relating to areas, where the reading data are recorded, on the optical discs indicated by the disc information, and priority information indicating priority ranks of the reading data;
- and
- controlling the disc apparatus so that data are read out preferentially in the order of high priority rank indicated by the priority information.
An information reproduction apparatus which contains plural optical discs as information recording media, the information reproduction apparatus comprising:
- plural magazines configured to be set at respective setting positions thereof, wherein the optical discs are set in the magazines in each of which plural optical discs can be set;
- plural drives each of which is configured to perform recording and reproduction on an optical disc set therein;
- a changer mechanism configured to transport a magazine between its setting position and one or more drives and mounts and remove a prescribed optical disc or discs in and from the one or more drives by performing either one of a single move process and a multi-move process;
- and
- a controller including a program that controls the information reproduction apparatus,
- wherein in the single move process, a prescribed optical disc that is set in the magazine is transported and mounted in and released from the drive while the magazine is reciprocated once between its setting position and the drive;
- wherein in the multi-move process, prescribed N optical discs that are set in the magazine are transported and mounted in and released from N respective drives while the magazine is reciprocated once between its setting position and the drives, N being an integer that is larger than or equal to 2;
- wherein the controller stores a reading data list information relating to all data to be read out, the reading data list containing disc information that enables identification of optical discs storing reading data to be read out, area information relating to areas, where the reading data are recorded, on the optical discs indicated by the disc information, and priority information indicating priority ranks of the reading data;
- and
- wherein the controller judges whether to conduct the single move process or the multi-move process as a transport process for transporting optical discs to respective drives to read data from them based on the reading data list and use statuses of the respective drives, and performs controls so that data are read out preferentially in the order of high priority rank indicated by the priority information.
