Abstract:
1. A data reproduction apparatus comprising: a synchronization information detection circuit for detecting synchronization information of a block to be reproduced from a recording medium in which a series of data string having said synchronization information added thereto is recorded as a block to produce a synchronization information detection signal; a block end position calculation circuit for calculating an end position of said block on said recording medium on a basis of said synchronization information detection signal; a data reproduction circuit for reading out data recorded from said detected synchronization information to said calculated end position of said block from said recording medium to reproduce the data; a data processing circuit for processing data produced from said data reproduction circuit after elapse of a reproduction delay time on the basis of said synchronization information detection signal; a first unit including said synchronization information detection circuit and said data reproduction circuit; and a second unit including said block end position calculation circuit and said data processing circuit, wherein said synchronization information detection signal is sent from said first unit to said second unit and said data is sent from said first unit to said second unit after said synchronization information detection signal has been sent and wherein said synchronization information detection signal and said data are sent from said first unit to said second unit through the same signal line and when synchronization information of a second block continuing to a first block is detected while said data reproduction circuit produces a data string of said first block, outputting of the data string of said first block is temporarily reserved and after said synchronization information detection circuit detects said synchronization information of said second block or after a predetermined time elapses from the time that said synchronization information is not detected, the outputting of the data string of said first block is resumed.
