Title: System and method for accessing tracks for optical disc apparatus
IPC: G11B21/08
Filed: 1988-11-18
Abstract: A system and method for accessing tracks for an optical disc apparatus are disclosed in which when a light spot is jumped toward a target track, an acceleration pulse is applied across a fine tracking actuator to accelerate the fine tracking actuator for a predetermined period of time, a relative speed of the light spot to the tracks of the optical disc is detected though a detection of a period of a traverse signal outputted due to a movement of the fine tracking actuator, and a control signal corresponding to the relative speed is used to control the movement speed of the fine tracking actuator. Therefore, before the end of a track jump, a constant relative speed can be achieved such that a smooth tracking servo can be carried out. Consequently, an access time to access the target track can be shortened.

Title: Checkpoint retry system
IPC: G06F12/08
Filed: 1989-05-17
Abstract: A checkpoint retry system for recovery from an error 
condition in a multiprocessor type central processing 
unit which may have a store-in or a store-through 
cache system. At detection of a checkpoint 
instruction, the system initiates action to save the 
content of the program status word, the floating point 
registers, the access registers and the general 
purpose registers until the store operations are 
completed for the checkpointed sequence. For 
processors which have a store-in cache, modified cache 
data is saved in a store buffer until the checkpointed 
instructions are completed and then written to a cache 
which is accessible to other processors in the system. 
For processors which utilize store-through cache, the 
modified data for the checkpointed instructions is 
also stored in the store buffer prior to storage in 
the system memory.
