A disk recording and reproducing apparatus which realizes a simultaneous recording function with a simple pickup system. The apparatus comprises a recording and reproducing head, a first memory for receiving and storing input signals at a first rate and supplying the stored signals at a second rate higher than the first rate so as to be recorded onto a disk medium at the second rate by the head, a second memory for receiving and storing signals reproduced at the second rate by the head and outputting the stored signals at a rate lower than the second rate, and control means for controlling the head to reproduce the Nth block (N is a natural number) and then repeating, while N is repetitively incremented, a sequence of operations of reproducing the N+1th block, moving to a position of the disk medium at which the Nth block is recorded, recording the input signals supplied thereto from the first memory means at the position of the disk medium at which the Nth block is recorded, and moving to another position of the disk medium at which the N+2th block is recorded.
An apparatus for recording and reproducing signals in data blocks onto and from a disk medium, comprising:
A method of recording and reproducing signals in a plurality of blocks onto and from a disk medium, wherein the signals are supplied to and stored into a first memory at a first rate and then outputted from the first memory to a recording and reproducing head at a second rate, which is higher than the first rate, to be recorded onto the disk medium and then the signals reproduced from the disk medium by the recording and reproducing head are supplied to and stored into a second memory at the second rate and outputted from the second memory at a rate lower than the second rate, comprising the steps of:
