CAV-type optical disk player having a pause function

A pause performing method for use in an optical disk player having a rotation information generator for generating information corresponding to rotation of a disk comprising the steps of:

• a) storing first position information which represents a pause position when a pause operation is performed;
• b) firstly jumping the pickup along a reproduction start direction by a predetermined number of tracks using disk rotation information which is supplied from the rotation information generator;
• c) comparing the stored first position information with second position information read out via a pickup;
• d) firstly reading out the second position information if a current position of the pickup does not pass the pause position of the disk according to the comparison result;
• e) allowing the pickup to travel along the disk tracks according to the pickup reproduction direction until a number of vertical sync signals read out from the disk equals a predetermined number, if the current position of the pickup passes the pause position of the disk according to the comparison result;
• f) secondly jumping the pickup along the reproduction start direction by the predetermined number of the tracks to a jump destination if the number of vertical sync signals read out from the disk by the travel of the pickup equals a predetermined number;
• g) secondly reading out the second position information while the pickup travels along the reproduction direction from the jump destination;
• and
• h) repeating the above steps (c) through (g) using the second position information read out by the above reading-out steps (d) and (g) until a signal discontinuing the pause performing method is received.

An optical disk player having a pause function comprising:

• key input means having a pause key for outputting a pause key signal;
• a disk which stores a plurality of position information addresses different from one another and data recorded on the disk;
• a pickup for reading the data recorded on the disk and the plurality of position information addresses;
• a memory for storing a first one of the position information addresses as a first position information address read out from a pause position of the disk via the pickup at a time when the pause key signal is applied via the key input means;
• and
• control means for receiving the pause key signal from the key input means to control the memory to store the first position information address, for controlling the pickup to travel on the track of the disk along a reproduction direction, for receiving the first position information address stored in the memory and second position information address currently read out via the pickup and corresponding to a current position, for judging if the current position exceeds the pause position, and for controlling a track jump of the pickup according to a result of the judgement.

A method of performing a pause function, for use in an optical disk player, comprising the steps of:

• a) reading frame address data and vertical sync signals from an optical disk by controlling a pickup to move in a downstream direction during a reproduction operation;
• b) responding to input of a pause signal by storing an initial current frame address in a memory, wherein the initial current frame address represents a desired pause location;
• c) proceeding with the reproduction operation by reading the frame address data from the optical disk and comparing a subsequent current frame address with the initial current frame address stored in the memory;
• d) if said comparing step yields a first comparison result indicating that the subsequent current frame address is smaller than the initial current frame address, controlling the optical pickup to jump back to an upstream track once a predetermined number of the vertical sync signals have been read from the disk, and again performing said comparing step;
• and
• e) if said comparing step yields a second comparison result indicating that the subsequent current frame address is not smaller than the initial current frame address, performing a temporary stop mode, to realize the pause function.

A method of performing a pause function, for use in an optical disk player, comprising the steps of:

• a) reading frame address data and vertical sync signals from an optical disk by controlling a pickup to move in a downstream direction during a reproduction operation;
• b) reading frequency generation pulses indicative of rotation of the optical disk;
• c) responding to input of a pause signal by storing an initial current frame address in a memory, wherein the initial current frame address represents a desired pause location;
• d) controlling the pickup to jump back to an upstream track once a predetermined number of the frequency generation pulses have been read;
• e) proceeding with the reproduction operation by reading the frame address data from the optical disk and comparing a subsequent current frame address with the initial current frame address stored in the memory;
• f) if said comparing step yields a first comparison result indicating that the subsequent current frame address is smaller than the initial current frame address, controlling the optical pickup to jump back to an upstream track once a predetermined number of the vertical sync signals have been read from the disk, and again performing said comparing step;
• and
• g) if said comparing step yields a second comparison result indicating that the subsequent current frame address is not smaller than the initial current frame address, performing a temporary stop mode, to realize the pause function.
