摘要:
In a drive system and a magnetic tape cartridge for use therewith, the magnetic tape cartridge contains a number of magnetic tapes, and the drive system contains at least a like number of read/write heads. The drive system includes a mechanism which is engageable with all of the magnetic tapes in the cartridge for simultaneously extracting all of the magnetic tapes from the cartridge and moving all of the magnetic tapes so that each tape engages with at least one of the read/write heads. Data can then be simultaneously transferred between the engaged tapes and read/write heads, so that the time needed to access data in a read mode, and the time needed to write data in a record mode, are correspondingly reduced by a multiple which is dependent on the number of tapes. All of the tapes are wound onto a single take-up reel.

Access time to data recorded on a tape in a tape cartridge is improved in a multi-tape cartridge and a drive for the multi-tape cartridge wherein a number of tapes having data recorded thereon are wound around hubs in the cartridge, and the tapes are separated as they traverse an opening in the cartridge. The drive system has multiple data transfer heads which are insertable into the opening in the cartridge and respectively engage the tapes in the cartridge. Data can be simultaneously transferred between the tapes and the heads. In comparison to a single tape having a given length, the multiple tapes in the cartridge can be shortened in length by a factor equal to the number of tapes, and the access to data recorded on the tapes is correspondingly faster by the same factor.
