Abstract

A method for successively reproducing video signals from both sides of a video disk in a video disk player. A spindle motor is driven to rotate the video disk. A first reproduction pickup reads the video signals recorded on a first side of the video disk moving from an inner circumference to an outer circumference of the first side of the video disk and a second reproduction pickup reads the video signals recorded on the second side of the video disk moving form an outer circumference to an inner circumference of the other side of the video disk and jumping a predetermined number of tracks to the outer circumference of the second side of the video disk every one rotation of the video disk during the movement. The read video signals from the first and second reproduction pickups are stored in a video memory unit. The stored video signals from the first side of the video disk are output from the video memory unit in their storage order to a screen and the stored video signals from the second side of the video disk are then output from the video memory unit in an opposite order from their storage order to the screen.

Claims

1. A method of successively reproducing video signals from both sides of a video disk in a video disk player, comprising the steps of:

(a) driving a spindle motor to rotate the video disk;

(b) reading video signals recorded on a first side of the video disk by moving a first pickup element from an inner circumference to an outer circumference of the first side of the video disk and then reading video signals recorded on a second side of the video disk by moving a second pickup element from an outer circumference to an inner circumference of the second side of the video disk;

(c) storing the video signals from the first side of the video disk and the video signals from the second side of the video disk, read in said step; and

(d) outputting the video signals from the first side of the video disk in an order in which the video signals from the first side were stored in said step (c) and then outputting the video signals from the second side of the video disk in an opposite order from an order in which the video signals from the second side were stored in said step (c).
