Patent number: 7099238Abstract: A method for the reproduction of data, such as digital audio data and/or video data, stored on a storage medium, for example, on an optical storage disk, in a playback device, in which an accelerated selection may be possible of storage media to be reproduced or to be rejected by playback device. In a first operating mode, data are filed in, for example, a nonvolatile memory during a play-back process of the storage medium. In a second operating mode, the storage medium is selected, for example, for a playback process and a reproduction process. Within a timespan during which the selected storage medium is brought from a magazine into a playback position, in which the data stored in the storage medium may be read out by a read device, or into an eject position, from which the selected storage medium may be retrieved, at least a part of the data filed in the memory is played back and reproduced.Type: GrantFiled: October 27, 2000Date of Patent: August 29, 2006Assignee: Robert Bosch GmbHInventors: Volker Becker, Holger Zimmermann, Dieter Baas

Patent number: 7092326Abstract: A player for storage media having a number of data groups is provided, which player enables a data group to be selected in a clearly organized way, particularly when a large number of data groups is stored on such a storage medium. In this context, a read head is provided for reading out the data of a first storage medium, and a read-head control is provided for positioning the read head in the area of a data group to be played, which data group is stored on the first storage medium. In addition, an input unit is provided where, on the one hand, various storage media and, on the other hand, various data groups, are selectable on a selected storage medium to be played. A conversion device is provided, which, in response to the number of data groups on the first storage medium exceeding a predefined value, forms at least two subsets from the number of data groups of the first storage medium, each of these subsets at the input unit being selectable as a different storage medium.Type: GrantFiled: September 20, 2002Date of Patent: August 15, 2006Assignee: Robert Bosch GmbHInventors: Volker Becker, Holger Zimmermann

Patent number: 7065007Abstract: A method for performing a track skip and a playback device for optical storage disks enable an accelerated track skip in the case of a non-moving storage disk in which a time is determined for the track skip of a read device between a current track and a selected track of a storage disk inserted in the playback device, as a function of the tracks to be skipped in this instance, and the read device is moved in the direction of the selected track for the determined time. In response to a track skip request, the read device is moved in the direction of a lead-in area of the optical storage disk until a starting position is detected. The time necessary for the track skip from starting position to the selected track is determined from this track.Type: GrantFiled: January 18, 2001Date of Patent: June 20, 2006Assignee: Robert Bosch GmbHInventors: Holger Zimmermann, Volker Becker, Jens Maier, Dieter Baas
