Recorded information reproduction method and recorded information reproduction apparatus with multiple reading elements

A method for reading data from N tracks (N being a positive integer greater than formed on a recording disk by N reading components, the method comprising the steps of:

• (a) rotating the recording disk in a reverse direction;
• (b) reading information corresponding to a single rotation of the recording disk by the N reading components in a reverse direction;
• (c) making the N information reading components jump over (N+1) tracks in a direction toward a last track from a first track of data to be reproduced;
• and
• (d) repeating steps (b) and (c) alternately until the reading of the data is completed.

A reproduction apparatus for reproducing data recorded on a recording disk, the apparatus comprising:

• a disk rotating device for rotating the recording disk in a reverse direction;
• N reading means (N being a positive integer greater than one) for reading data from each of N tracks formed on the recording disk to obtain a reading signal;
• reverse data reproduction means for reproducing data by demodulating the reading signal in reverse order;
• and
• track jump means for making the N reading means jump over (N+1) tracks in a direction toward a last track from a first track of the data to be reproduced.

A reproduction apparatus for reproducing data recorded on a disk having a plurality of tracks, the apparatus comprising:

• a spindle motor for rotating the disk;
• N reading components (N being a positive integer greater than one) for respectively producing N analog reading signals representing data recorded on the disk;
• N data reproduction circuits for converting the N analog reading signals to N serial digital signals;
• N memories for storing the N serial digital signals;
• track jump means for moving the N reading components over adjacent N+1 tracks of the plurality of tracks;
• and
• a central processing unit for controlling operations of the N reading means, the N data reproduction circuits, the N memories, and the track jump components, and for rearranging the N serial digital signals so as to output a reproduction signal corresponding to the data recorded on the disk.
