Multi-erasure locally recoverable codes (ME-LRCs) are an important class of locally recoverable codes (LRCs) with more constraints on the parameters. In this work, we present a new upper bound for ME-LRCs, which is tighter than that proposed by Cadambe and Mazumdar. The technique is to utilize the largest possible weight of linear codes to control the minimum distance. In addition, we present explicit constructions of ME-LRCs to achieve the proposed bound.
