ABSTRACT:
The invention relates to a reproduction apparatus having a buffer for reducing the mean access time to an information carrier which has for example a discontinuous data structure or a relatively long access time. For writing sectors to the buffer and for finding sectors in the buffer, a control table with a number of place holders and three variables is provided, the place holders in each case pointing with an index to a subsequent place holder in an endless chain of place holders which is divided into three regions, in which a predetermined sector in the order in the respective region is identified by one of the variables. Even though only one row of place holders is provided, multiple access to a plurality of sectors written to the buffer is made possible with a low outlay by means of the control table, so that the number of slower accesses to the information carrier is reduced and the mean access time is shortened. Application is envisaged for reproduction apparatuses with a small storage space, such as, for example, a DVD reproduction apparatus.
