Apparatus and method for magnetic tape drive control

摘要

A tape drive control apparatus and method for a magnetic tape recording and reproducing system are provided to prevent a failure of the read and write operations due to frequent start and stop actions of the magnetic tape. The magnetic tape has a certain resonance frequency between a read/write magnetic head and a tape guide of the system. When the rate of start and stop actions of the tape approaches the resonance frequency adverse vibration of the tape becomes large in magnitude. To prevent such tape vibration delay a delay circuit is provided to delay the start of the magnetic tape for the subsequent data block when the length of the preceding data block is within a predetermined range.
